Samsung galaxy S3 OTG for USB 3. hard drives

Hi there,
I have a samsung galaxy S3 (rooted) and have recently purchased OTG cable. The problem is that when I connect s3 with Hitachi Touro (mobile USB 3.0) through OTG cable hard drive does appear in files. I have installed paragon NTFS and stickmount apps but it doesn't seem to connect even though a message keeps appearing "usb connector is connected". Hard drive gives a clicking sound when it is connected with S3 but works perfectly with the computer.
Does anyone know solution to this?
Thanks and regards

I've heard of some people having problems when connected to a usb 3.0 port on their computer and have to connect to a 2.0 port instead. Maybe related?

USB 3.0 I don't think is supported. What I've seen people do is use a 2.0 cable extension with their 3.0 device. As this downgrades it to 2.0 because they should be compatible with 2.0 just won't have the insane speeds as 3.0. Or you can get a USB hub and plug it in that way.

Sounds like the Hard Drive is not getting enough power (The clicking), do you have it plugged into an external power supply?

Thanks for all the replies. Hard drive is not connected to power supply as it is portable.

Splatdotsplat is correct. That clicking sound are the heads resetting to the park position. This usually happens when drives are not getting enough power. When the drive spins up it peaks its power consumption and cuts out because there is not enough so the heads reset. Portable or not that is the issue. I have seen this happen with some portable drives on computers (especially larger capacity). A lot of times the solution can be as simple as using a shorter cable. Sometimes it doesn't work.

as stated above, the only way to run external hdd's of any kind is to be sure they're powered, even some thumbdrives will draw more power than the phone can provide and you'll notice your batt life take a steep dive (as did my Galaxy Nexus w/otg on an HP 16gb thumbdrive)
power the drive through a powered hub and you're good to go!

This is why i recommended using a USB powered HUB as the HUB will give enough power to the external hard drive.

Having the same issue myself, otg cable with Samsung portable 500GB external HDD and stickmount pro works fine with my Nexus 7,but won't work with my Galaxy even though it recognises the HDD, so do you think a USB hub would be the solution, and can anyone recommend one
Thanks

Anyone?

i wish there are people who are willing to investigate/try this thing out, it would be awesome to make a portable hard drive works on our S3..

Just to throw in some info. I do agree about the hdd not getting enough power as the cause for the clicking. I have a 500gb hitachi drive that does that if a long usb cable is used. The drive didn't come with a power adapter but instead came with a short usb cable that had two heads. allowing it to draw power from two ports. It also had a port for an adaptor though.
When testing with my Samsung Galaxy sIII It doesn't work unless I have the hd running via external power or have the second usb connector on the cable connected to a charging usb cable. Both options charge the phone while the hd is connected to the phone.
The usb cable with the double ports actually works well for me. I have the first port connected to the otg cable that I made and the second connection connected to a usb extender that is connected to my 2A tablet charger. That way I can charge at the same time.

Hi the problem i basically power as in the amount of current your device requires, i know that the standard specifications of the original 2.0 interface is about max 500mA and 5Vdc per port, in some cases the maximum output current is even smaller due to hardware restrictions, this can lead to difficulties when trying to power something like an external hard drive. Therefore a long cable will also give a problem due to the resistance of the material, because the required voltage level is not high enough.
I do not know if there is a spec sheet containing information about the output capabilities of the usb port, if there is one i recommend using that to match an external hard drives, if you do not want to use an external power supply.
Edit: you could also use an external power bank/battery pack but i seems a bit bulky

Sure go out and buy me one and i'll test all day..
USB OTG works out of the box for low power devices. I havent seen/read anything stating USB 3.0 works on the S3. I have a 1TB hard drive my brother gave me, its not the newer ones that are ssd so it has a power adapter with it and it works perfectly with my S3. Going to be using it in a few minutes to back up my internal SD.

So guys I have the GT-I9300 ( Galaxy S3 ) and I have 1 TB WD My Passport
I'm plannig to buy the OTG piece ! so as of now is possible to connect the hardrive to the phone or not yet !?

Is there even a driver and an app to do such a thing? As I see it the USB port is configured as an external storage device to connect to a computer not the other way around. What you are doing is connecting two storage devices together. There's no way I would ever connect anything to my phones USB port that requires power. If I were to, it would be through a powered hub.

I have read that you connected your S3 with external powered HDD. I bought yesterday the genuine samsung OTG cable and it is working only with memory stick and joystick controller. Don't know why it is not working with my external powered HDD - 500 GB WD. Any ideea ? My S3 is not rooted.
Thanks,
M.

No, nobody is going to have a recommendation for a powered USB hub.
It's a trivial, generic, piece of kit you buy nearly anywhere for under US$10 (unless you're a complete sucker.) Just make sure whatever you get *includes* a power supply.
Get one in the shape of a person, or a kitty cat, or a Tardis, whatever thrills you.

that's not quite accurate. when you plug your phone into your PC, the drivers that you installed will see your phone as a usb device (or media device) and allow you to use your phone as such
an OTG (on-the-go) cable allows you to connect a storage device to your phone, such as a thumb drive or external hard drive (powered or not) and then your phone acts like your PC and uses that device as storage

I can confirm that in my case forcing my ADATA HV610 1 TB disk to USB 2.0 mode worked. The trick is to use a standard micro-USB cable (e.g. the one that comes with your charger) instead of the standard cable that comes with the HDD.
More detail:
The common USB 3 cable which comes with most new HDDs uses USB 3.0 Micro-B plug which, in practice, is a micro-USB with a "half-micro-USB" next to it. The part most people don't know is that you can use a common micro-USB cable (as the one from your charger) to connect your HDD to your PC (or other device) with the cost of loss of USB 3.0 compatibility. Which, in our case, is what we need, as this switch makes the HDD less power-hungry.
Post a comment if it works for other hard drives too (I think WD also use Micro-B connectors for their USB 3.0 Passports)

[Discussion] Working OTG Devices

***EDIT***
USB Host DOES work with Flash Drives. For information see post 3: http://forum.xda-developers.com/showthread.php?p=37201971#post37201971
This is now my main focus. So I figure why not everyone post up what devices they got to work with the Kindle Fire 2 and/or what methods it took for you to do so.
3x Different Flash Drives: Not Working However one of their LED's Illuminate
USB Keyboard: Not Working
Logitech M570 Wireless Trackball: Working
I also tried a non powered hub, it didn't work. The Green LED Illuminated but nothing more. When connected to my Galaxy S 3 I can have multiple devices attached at a time. I tore the Hub down and found that it has a blank slot for power. I wired soldered in a 0.75a Samsung Wired Charger to it. It Illuminated the LED, As well as it illuminated the Power LED in Orange on the Kindle but no devices worked on the Hub. I tested the power output of the USB Ports and it was a little more than 5v per port.
Device: Kindle Fire 2
Rooted and TWRP'ed with the Nightly of CM10.1 1-20-2013
Will keep trying. As stated in another thread, that its simply power. After testing these things out, I don't think its power related. Either the kindle just doesn't have the "Drivers" if thats what you'd call it, or it simply can not run anything but a mouse. I hope that is not the case. It will ruin all appeal in my eyes.

If you're rooted, have you tried installing StickMount?
Might work for the flash drives.

I tried, Stickmount tries. You can tell its trying to work something out. So more tests with a cut up usb cable on the OTG cable does in fact show there is a voltage issue. My Galaxy puts out perfect 5v. The Kindle puts out around 2.5v. I tried making another OTG cable but failed. I guess its just not getting connection to the extra pin. So I have a USB Extension I'm gonna split open and power it. So I don't have to hack up my only working OTG.
The main issue I'm having with this is, my current power unit is a measly 0.75a. And It charges the device. So I figure there will still be a voltage issue due to the device charging. So I could cut the red wire going to the device for now. But not sure if the device will realize this somehow and just not work. Thoughts? I've seen this done before when someone made themselves a powered OTG Hub system out of a couple USB Cables.
I'll continue till I'm too tired to think hehe.
***Edit***
Ok couple hours later.... lol I had a USB Extension, I cleanly just slit it down the m iddle and soldered in the two power wires from a samsung micro usb charger. The Power is 5v at 0.75a. So its not much. I know it wouldn't charge my nexus nor Galaxy Tab, but it charges the Kindle, or at least the kindle says it is. I doubt it really is. Anyway I soldered it in, cleaned up the surgery started some testing on my phone first. I connected a Micro USB cable to one end and then the other to my phone, and then the Kindle. It charges, or again says it is (*kindle might require more amperage). So Next I connect the OTG Cable to the other end and connect it to my phone, It charges through the OTG Cable. Next the Kindle, it does not charge the kindle. Possible amperage requirements, I don't know yet.
So onto the test without StickMount, Failure. It acts the same.
Test with StickMount, Well I'll let this screen shot explain most of it:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
It worked! StickMount notification pops up and I found the flash drive in the current location. Inside the SD Card under a folder called /usbstorage/sda1/. Not exactly my first choice, not sure if this can be changed to go into mnt or somewhere else. The Device itself doesn't notice the flash drive. So if you go into System/Storage, it does not show the flash drive. But it is fully functional. I accessed some files without any issues.
So my final consensus: The Kindle Fire 2 currently has OTG/USB Host Capabilities. From the USB Host Diagnostics I ran, its fully functional. However the main issue is Power. The second issue is the device on the most current (1/20/2013 CM10.1 Nightly) rom doesn't have the proper... I don't know the right wording for it, but lets say drivers since I'm a pc guy. I'm sure with more development, it can control any device with the only issue being power related. This takes away from the meaning of "On The Go". Having some sort of 5v power source connected to your device while your trying to use a hard drive or something else is going to be a pain in the ass for most people. For me it really does not matter since the device is going to be setup in my car for media sourcing as well as game play. So a 32gb flash drive and a Xbox 360 controller is all I will be using.
I will be doing more testing with multiple devices but it is 4am right now. One more thing, Bluetooth abilities are possible with a cheap dongle. However for some reason the Kindle recognizes it as a physical keyboard. I have tested this on other devices in the past so I believe it is possible with some more development. But that's far in the future and still of course require additional power.
Goodnight guys.

I have 3 different thumb drives.
Sony 4GB = does not work
SanDisk cruzer slide 16GB = does not work
SanDisk cruzer 8GB = Works
The regular cruzer is probably 5+ years old. I have access to others and will update my post when I get them.
I'm on PowerPoint45 cm 10.1 using chainfires stickmount.

Nice. The regular flash prob requires less power. I noticed one of mine which was larger almost worked. But would shut off prob to not enough power. But a newer one wouldn't light up at all.
Plans for today: To re build that USB Hub I was messing with last night. I desoldered the USB cable off of it to solder in a Micro USB, But I don't remember if it worked. I then tried to turn it into an OTG direct 4port hub but nothing happened. So I'm sure I screwed something up. But the initial results should be a powered, 4port Micro USB OTG Hub. I just hope I have enough juice to make it work for not only charging the Kindle but powering the devices on the hub. I have a Galaxy Tab Official 2.0a car charger I can try out. I want to be able to have at the least, a 32gb Flash Drive and a 360 Gaming Controller.

Well I got some done today. I found an old phone charger that was 1a. I finally just used my OTG Cable and soldered it in place of the std usb connector on a cheap USB Hub. I'm sure everyone has the same hub I'm using, I have two, one says Microsoft on it, the other says AMD but they are super cheap and are given out everywhere you go:
Its a non powered USB hub, however when opened up there is a bare spot for a power connector. Middle pin is 5v + and the two around it are common Ground -.
Don't be strayed by my crap solder work. I'm using a cheap harbor freight soldering iron and the new charger has very thick wire so it didn't really fit in the small holes. The ground is just directly connected to everything else thats ground related so I grounded it there. That way the two wires aren't soo close together.
I have now successfully tested 3 flash drives, NTFS, Fat32 and some strange Fat32 drive plus my Trackball. As well as this I have successfully charged my Galaxy SIII off of the hub. I wouldn't exactly recommend this unless your running like a legit 2a charger. I only did it to test out power requirements. I think either my cable is damaged too or I'm at the limit of power the small 1a can handle because every once in a while the hub shuts off. I think its just cable related.
Here is everything connected as you can see.
However the tablet it self is not charging. At least the icon on the notification bar doesn't say so. I have tested the voltage here and its 5v. But IDK? Maybe the Kindle wont allow it? BUT, with all my testing, the battery has stayed at 88%. I'm gonna try to kill it some more. Maybe with some transferring files between drives.
lol As I'm typing this, I sit down for a second with the tablet on the carpet floor and just stare at it. I've noticed that some reason the led turns off and on at random times. But I've never seen it say its charging. Well the screen just dimmed but didn't shut off so I get up to check real fast and when I turn it on, it says 88% - Charging! But then instantly goes back to 88% - Not Charging when the screen lights up. And there it goes again (Please bare with me as I'm doing this all this very second.) Looks like it just needs some more amperage. 1a is not enough to power everything and charge the device.
I was worried that the kindle wasn't going to support Charging OTG. Well I happen to have a spare 2a Galaxy Tablet charger and no Galaxy Tab.... I'll try it out and get back to you guys!

This looks good! If you want, once you are done with the testing, I can try and write up a guide with your words on how to do it then let you post that. I did the same for some of the stickied threads. It looks like you're almost done and I think this would be a really good info thread once compiled nicely. Stuff like how to do OTG, what works, what needs a powered HUB, stuff like that. I personally will probably never use OTG, but I see the value and I like what it can be used for.
Best of luck!

That's nice. lol I understand I talk a lot, but when it comes to things I must have, like more than 5gb of memory on a device that should have a few TB . It would be nice for others to try out things to see what works and what doesn't. Because to have a powered USB Device is kinda not the point of OTG "On The Go". But like someone figured out that one of his older Flash drives worked, so hopefully others chime in too.
If you wanna do that, you have my approval. Just make sure it suits what I did, "Dedicated OTG". or "Guaranteed OTG". Since that's what I was mainly working towards. This discussion thread is mainly to locate what works and what doesn't and the main OTG Capabilities of the Kindle Fire2. I don't plan on changing much else to what I have already done except adding a larger psu to the hub so it charges the device while powering the hub and its devices for my own personal gain. I want to keep this open so people can throw up what they have learned as well so the information is out there for others. I personally hate going into a device and not knowing.

I should get an OTG cable. I have a small flashdrive, not sure about the name or brand since the size made it temporarily misplaced. It's the same size as the wireless receivers though for most modern mice and keyboard so it's SUPER small, which I actually wouldn't mind tucking the cable into my case, plus it's 32GB. The issue on PC, is the transfer rate is a little low, but that may be because it uses so little power, which I'm hoping.
Any good places to get an OTG cable?

Ebay, Amazon (great place for cables)
https://www.google.com/search?q=OTG...29,d.aWc&fp=4a19662fa4882be9&biw=1920&bih=965
Just a quick search. You can also make one, if space is an issue. You just need a MicroUSB and a female USB. Pin 5 gets soldered to pin 4 on the MicroUSB and bam! Making one would help with space issues since you can tuck the wires easier. If you are good at soldering.

Is an OTG cable special or just F-USB and M-MicoUSB?
If it's just those, then I can go poke around Frys and Radioshack for one.
I don't know anything about soldering, how much is a good kit to get started? I think a friend of mine has one and knows how to use it, so I can ask him, but I realize it's something I should learn especially with the hardware mods I would love to do. If I can't find a cable in stores, or if it's special (I ask that because most employees at frys and whatnot aren't very helpful or knowledgable, so I don't want them giving me something that won't work, but if it's just those ends I'm looking for, I can do that) then I may just look into soldering my own and learning that. I see they're around $50 online but I don't want to screw myself over there.

You can chose a decent soldering iron anywhere from 15 to like 80 bucks. I recently saw some nice ones with adjustable power levels for good price. And tons of different tips. My brother Skorpn has the more expensive one that heats up fast and has adjustable power settings to fit any projects needs. Hr has a nice soldering station I wish I could use more. I however just have a cheap harbor freight iron with a fine tip from radio shack and I use the thinnest silver solder avail there as well. Flux is also a must.
Anyway. Otg mode is accomplished on the micro USB side. They have 5 pins instead of 4. The 5th is used for doing all sorts of things with the right add one tho. If you solder in a small wire to it and jump it to pin 4 which is ground, it turns on otg. Not really hard to do. You can make one decently. Just need a good micro USB cable and a female normal USB cable. Solder them together and then do the otg modifications.
Other than doing it yourself, they are very cheap. But if you have the spare cables, it doesn't hurt to play around.

I've got my USB mouse to work using otg cable, is there any chance using it could damage my kindle, this Mount app I use says it can damage the kindle because of the power output

I don't know what ap your talking about. But no. The Kindle Fire 2 only puts out half the voltage when in OTG Mode. So only certain things will work without additional power. Your mouse will work just fine, especially if its a wireless mouse, since the wireless device doesn't require hardly any power. Some other devices will work too. You don't need a mount app for using devices, only for Flash Drives. And so far out of every one I've used the best one is Chainfire's StickMount. Chainfire is the creator of Superuser.
Anyways, I'm not using a 2a charger to power my USB OTG Hub, and it powers all 4 devices and charges the device with ease. Cannot wait to have this thing installed.

OTG testing
After reading this thread I thought I would have a go and do some testing myself. so I found a USB y cable teamed that with a female to female USB adaptor so it would extend my OTG cable but allow me to pipe in some power (5v off a arduino) off the y cable. I have got my mouse working and USB flash drive but I cant get my Xbox 360 wired controller to work

You know the amperage of the power source you are using? It might just be not enough power. Because the device itself will take from it also. Its pretty much splitting it. Which is why I went with a legit Galaxy Tab 2a charger since its one of the most powerful chargers I've come across. I hope it works. Since bluetooth doesn't work on the OTG yet, I need the 360 controller to work. I will be trying a wireless controller and one of those Microsoft adapters soon. Hopefully it works! I'd love to play some video games in the car

You have a good point there, I haven't tested the amperage that comes out of a arduino but I don't think it would be much. I could try and hock up a iPad charger which I think is 2amp.

I have just tested the Xbox 360 controller being powered from a iPad charging plug and now joy. It lights up but then goes off

I'm making my own otg cable tonight if the spare usb cable I found works for data and not just charging. Basically I have a female usb port on a cable that I used to splice in with an original Xbox controller plug to be able to use usb sticks as memory cards for my Xbox to be able to install gentoo Linux on my Xbox (original Xbox controllers are usb 1.0 with a proprietary plug type) so I know the female port works fine for data transfers.
Eventually I'll buy some plugs to solder onto both the usb and Xbox cables so I can yank the female plug from the otg cable and snap it right onto the Xbox plug instead of having to constantly re-splice them or buy a new usb extension cable for the female end/buy a pre made otg cable.

IDK how thats going. I don't think anyone is working on it since the KF2 doesn't have bluetooth to begin with. When I connect my cheapo BT Dongle, it doesn't allow me to turn the switch to on. However it does see the BT Dongle and thinks its a keyboard of some sort. Which would be nice because I have a really nice BT Keyboard for Android I wanna use.
Also would be nice to use PS3 Controllers. I'm going to attempt the wireless 360 controller with the adapter one of these days, whenever I can focus some cash in that direction. I really want a wireless 360 controller on my KF2 so I can play some of the higher end games as well as the older Emulated games. Just think its too cool

OTG adapter

Bought two OTG adapters on eBay, they arrived from China today. When I attach them they are both recognized by the system. However, when I insert a USB memory stick I receive an error message about "high powered USB device" and the system won't acknowledge the presence of a memory stick. But, if I insert the Samsung OTG adapter I have no problem getting the same memory sticks accepted.
Is there anything I can do to correct this? Or have I just wasted $13? (I'm not gonna cry if that is the case)

It is possible the active components in those adaptors plus the USB stick is pushing the consumption over the edge, where the simple Samsung adaptor does not.
I also have one of those adaptors by the way but have not had the same problem so far. Maybe my USB stick needs less power.

The one with the cord seems to have a connector, but the other doesn't. I suppose the 5V standard is applicable.

Try connecting everything together then connecting the OTG adapter to the Note. I have the same issue sometimes when connecting any device if the adapter is already connected.

did you check if there is a small button to change mode on the hubs ?

Once in a while I had the same issue with the original adapter. With the new ones I don't get the error message but neither is the presence of the USB memory acknowledged. The larger one with cord has a blue power light that goes on. It turns off when I insert the stick but stay on when I insert it joint with the OTG adapter.

I have an OTG adapter that's jsut a data-port-plug then a cable leading to a female-USB, I've had a lot of issues with USB devices being classified as "high power" and not working (including an Xbox360 controller, which has been listed on this site as usable without external power) I've tried 5 different hubs, and only 1 will work (3 brand-name (2x Ultra, 1xBelkin) and 2 unbranded from china) that's the one that accepts external power.
I could be wrong but I think they pulled the same trick apple did and an update lowered the power to the docking port, so you HAVE to use a powered hub to do much of anything... (though for the record, none of my 4 USB sticks (1gb, 4gb, 64gb, 64gb) have required external power...)

Yeah, it surprised me to get that error on a memory stick, I didn't think they used much voltage.

So, now I have tried all possible connections to see if I could get the OTG adapters to work. The short answer is that they are rubbish.
I connected older (USB 1.0 and 2.0) memory sticks to no avail. Granted I didn't get the high power error message, but I didn't get anything else either, least of all access to my files. So that was out. I then connected a USB keyboard, again I received the high power error message and couldn't use the keyboard. Finally I connected a portable charger to the larger (5-in-1) connecter, the one with the cable, in order to see if that would help. All it did was burn the inside, took a few moments and then smoke started to come out together with the unmistakable smell of burnt copper.
Anyone, interested in these connectors would be wise to proceed with caution. Yes, the price is alluring, but if value is zero then anything over zero is too expensive.

Looks like the ability to connect a USB stick is questionable. I just got an adaptor, the one that is just cable with female usb on one end. I plug it in and the device says USB connected. Doesn't recognize the card. But I do not get the error about "high power device" that everyone is referring to. It just doesn't recognize the card.
I used two cards. One is an Attache 16gb that has a rather bright light on it. On the laptop, when its plugged in, it stays on, and blinks when being accessed. When I plug it in to the tablet, the light comes on for a couple seconds, goes out, and nothing.
The other one is a PNY 16gb with no light. I tried it thinking the light might have thrown the Attache over the edge. The PNY doesn't seem to be recognized either. No errors. Just no response.
Is there a mount or something I have to do somewhere? Documentation with this thing is less than stellar so if there IS a document that answers this, I haven't found it.
Thanks.
EDIT: I tried with a powered USB hub and it worked. So its definitely a level of power issue. Now the trick is to find a way to have portable power on the hub. I recently tried using one of the portable cell phone power packs but I think it may have been defective as it would not charge up. I had purchased a solar powered USB hub but it worked once then ceased forever to function.

Connecting USB storage Drive and HDMI out

Hi I just recently purchased the Samsung galaxy tab s 8.4. What I am wondering is how can I connect a full size usb flash drive? Can I buy any old cheap usb to micro usb adapter and it should work? Or do I need some sort of special type.
I was also wondering how I can get video out onto a TV through the HDMI port. Will any micro HDMI to full HDMI work? Or do I need a specific special type.
Thanks in advance for any help or input related to this.

Buy a media dock to use both mhl and otg simultaneously or an otg adapter for flash drives and a Samsung specific mhl/HDMI cable for video out.

Im sorry but i don't exactly know what your talking about when you say media dock.
Can I buy any micro USB to HDMI adapter and a micro USB to USB adapter Or do I need specific cables straight from samsung? Theres several of these cables being sold at my local NCIX computer store. This forum will not allow me to post the links however.

Got mine off eBay....
eBay LINK ... MHL OTG Hub
Link to full eBay search... (choices bro)
.
.
.
I also use one like this at work... (don't need MHL there)
eBay link ... OTG Hub
It has 3 USB ports and several different card readers... I can run that with a 1 Terabyte Hard drive, 256GB Flash Drive , 128GB micro SD card , wireless keyboard and mouse... all running off that hub simultaneously.... all working as they should.
Pro Tip... Always use the MHL/OTG Power input when running powered devices... DON'T try to power from your tablet...
The first item I listed in this post (MHL OTG Hub) has a micro USB port... plug your Samsung charger in there before plugging in any other devices and before plugging into your tablet
The second item has its own dedicated power cord supplied with the device which can also be plugged into your Sammy charger to run the power side of the hub...
Failure to do this can burn out the 5 volt rail on your tablet... you will also notice all sorts of problems with devices not being recognized by the tablet when external power is not plugged into the proper port on the hub.
Many of these "hubs" come from China with sketchy instructions... they try but it gets lost in translation I suppose.
Here's what I learned over time...
when using a hard drive or wireless keyboard with a hub
plug in your external power to the hub first
then plug in your hard drive or wireless keyboard/mouse dongle
then plug the hub into the tablet
If you do things in the wrong order the tablet doesn't recognize the drive or device
Those steps are not necessary for memory cards and flash drives.

Thats awesome its definitely a handy cord to have.
I was wondering if you know should pretty much any mhl otg hub work with the Tab S? There is several listed on eBay with various prices. Are all of them made equal? or is it possible that certain ones wont work. Ill probably just order the one you linked because you have confirmed it does in fact work with the Tab S even though its not listed as a compatible device.

Works... i used it just a couple hours ago to dump movie downloads onto my hard drive and clear up memory...
But now that you mention it... i haven't tried the MHL function to HDMI with the Tab S yet because i have chromecast now and I'll mostly stream from the hard drive right through to the chromecast.... i can test that tomorrow if you want a rock solid answer before you buy... i have a half day on the crane tomorrow so it would be after 12:00pm EST when i get home and try plugging it all in.

Any of the newer Samsung devices from the s2/note2 and up should have the dual functionality USB port. You can, with a good eye, and good lighting, look at the port and see the 2nd row of pins. If it has/supports mhl out, it will do simultaneous otg as well. This is exclusive to Samsung devices.

Hey man I just received my adapter in the mail today but the HDMI out is not working do you have any mtips on how to get it to work? I connect my power source first and then connect my HDMI but still nothing works. I bought the one you mentioned but its a bit different from what you have pictured. Any help is greatly appreciated.
Edit*
Ok I finally got it working. I had to connect my device to it first before the power source or it wouldn't work. I know you mentioned this can be hard on the battery but its the only way I got it working.
I connect my power source after the HDMI out is up and running but my battery seems to still be draining fairly quick. Does that mean the outside power source is doing nothing? Am I doing harm to my tablets battery?

hello, im thinking about buy one of these, my question is, does that white cable charge the device?
cause i want to charge the device while using this function, can anyone confirm this, and in case it doesnt charge, can we mod it to do it

Anyone tested OTG?

I've tried a One plus 2 adapter and a normal one. Nothing is detected.

I 've tested with a third party adaptator (shipped on Amazon) and it work fine with OP3, but not with OP2 ...

But any USB-A flash drive or SD reader, etc. that I connect to the apple adapter, works.
I just bought a 4-pack of cheap USB-C to microUSB tips from amazon, and none of them work to connect the microUSB side of my Samsung OTG flash drive. Interestingly, they all work fine to transfer files to my Mac and for charging, but the Tech-Matte tip only charges and does not sync (although it claims to be able to).

Are the adapters you are using specifically OTG-enabled or just pass-through?
While the Oneplus cable is OTG, you must be using some sort of microUSB to USB-C tip adapter, right? Maybe that is the problem, since none of my tip adapters work with OTG either.

No, they are otg enabled, BTW many others also reported no otg with One plus two adapter on OP3.

OnePlus adapter didn't work for me either. Worked perfectly with the OP2, but not on the OP3. And yes, I did enable OTG, no help. Not sure what the problem is. Going to wait a few days to see if anybody else has something to add.

I bought an adapter from amazon store, maybe is a little cheap, but It works fine with my mouse (bluetooth adapter for Trust GTX 120), but it won't work with any of my external hard drive with external power source (some 2.0, some 3.0), neither with more simple usb pen drive (2.0), neither with my ps4 controller.
If I try to connect one of my pen drive, with the OTG option active, ES File Explorer show me the pen drive and the dimension, total and free, but doesn't shows any files, and I cannot write on the pen.. is that a normal behavior for a not-working adapter or is a problem of different kind? The mouse is working so there is something that is working.. Am I wrong?
Edit1: I've tried with NTFS format, once even with fat32 and ex-fat, the ntfs one seems to be the best try
Edit2: OTG Troubshooter says that everything should be fine
Edit3: Done. I could read just one time the usb pen, the cause it's the cheap adaptor in the end

With the Apple adapter would I be able to use that with any usb drive or am I limited to 128 GB or something? I have all my movies on my computer but I'd like to be able to put them on a flash drive and then stream them from my phone to my Chromecast. I'd need at least a 256GB drive though.

I use a USB2.0 / USB-c stick.

Strange thing is: The Oneplus 3 (Oxygen OS) recognizes it, but when i want to do a Nandroid-backup: TWRP does not recognize it...

In the TWRP thread it's been mentioned that OTG doesn't work yet.

With the apple adapter I linked to above, you can use any usb drive. I've successfully used it with multiple usb flash drives as well as a usb SD reader with a microSD card inside an SD adapter.

No OTG support - Oneplus Type C adapter
I am also tried to connect a usb drive using oneplus type C adapter. but it is not being detected.
