Can't Get Mirco to USB OTG to work - Galaxy Tab S Q&A, Help & Troubleshooting

Hey Guys,
I recently bought a Micro to USB OTG cable but unfortunately can't get it to work on my new S Tab(10.5).
I am able to get it to work on my Galaxy S3 phone and old Nexus 7 tab so it appears that the cable works fine. My S Tab is not rooted and currently does have the latest updates. I also ran the OTG checker which verifies that my tablet has the necessary files. When I run the OTG troubleshooter tho it does not appear to be picking up my cable at all.
I originally bought this to use my wired 360 controller on my tablet, the 360 controller and flash memory sticks are the only things I have tested on the cable itself. Like I said above, my S3 and Nexus 7 picks up these 2 devices just fine through the cable.
Anything that I am missing? Any tips/quirks to get this to work?
Thanks so much for your time/help!
P.S. attempted to post link to my exact cable but couldn't because I am a new member.

Are you willing to have device root and flash a custom kernel?
If yes, then my SkyHigh kernel does support OTG and has in-built XPAD (XBOX) controller module and confirmed working by another user. Some games may require you to map the controller with a certain app, some without.
FS support is dependent on kernel. If you are trying to mount NTFS r/w, then you will need to also install Paragon app or navigate to /mnt/ntfs/.... for kernel NTFS r/o

It's possible that it could be your cable. I had problems a couple years ago with an otg cable not working on my Note 2 but working in a couple older devices. It turns out it was because the micro usb end that plugs into the phone was too short to plug in all the way. I'm not sure if it's a new standard or something, but my Note 2, Note 8, S5 and Tab S all seem to have a cable with a longer micro usb tip than any of my previous devices have.
Hold the otg cable next to the charge cable that came with your Tab S and see if the tip of the otg cable is a couple of millimetres shorter. Also plug the charge cable into the tab and notice the way it kind of "clicks" into place when you push it in the last little bit. Now plug in the otg cable and see if it has the same "click" feel. If not, then I'd bet it's your cable. I have an otg cable that specifically states that it's for an S5 and it works perfectly on all the devices mentioned above. I also have a generic otg cable that works on my old galaxy nexus but doesn't work on any of the above devices.
Here's the old thread in case that helps:

Thanks for the reply's.
I don't really want to go down the Root road because I have never gone through that process and don't feel comfortable with it at this time.
The cable Micro pin portion definitely doesn't fit as snug as the S Tab charger. The OTG cable actually appears to be longer than my S Tab charger Mirco pin. When plugged in you can tell it sticks out a smidge....The thing with that though, it does the same exact thing on my other 2 devices that work with the cable.
Guess it could be the cable, just hate to send this back and order another and be in the same boat.

Cable or no cable, if you wish XPAD controller, then you'll need the kernel or loadable kernel compiled module. Other features (some I described) also require kernel. ... all requiring root.
Since you've ruled that out, you just need to forget many features that are available with some other devices and move on.
Best of luck.

USB cable "OTG" not working am I doing it wrong?

I got a Micro-USB to USB (female) cable form ebay... from China (I didn't know until I chekced later. I usually have the "UK sellers only" option checked).
Anyway, after an eternity, it arrived today. But, it doesn't work when I plug it in. Nothing happens. My Sandisk Cruzer doesn't light up when I plug it in or anything.
I was on the ninphetamin3 Kernel, and I've tried the Siyah kernel, just in case it's the kernel that was limiting functionality... Apparently it's not because it still doesn't work.
It only cost a couple of quid, but is there something I might be missing that I can check before buying another from the UK?

That is not necessarily an OTG cable... did it SAY it was an OTG cable? If not, it probably isnt. Pin 4 and 5 need to be connected (in the micro usb side) for it trigger OTG functionality. if it is not working it means one of 2 things:
1. You didn't buy and OTG cable, you just bought a cable with the ends you wanted, but without the funtionality
2. Something is broken on your phone... test that cable in another phone with OTG capability (go to a verizon store if you have to)
3. I think i remember seeing you need an app to use some flash drives (keybaords and mice work without any app, i can attest to that from experience)

That's the one I got. It's 5pin, but you're right in that it doesn't say it was OTG.
I don't have another OTG compatible device to test with
I got an OTG cable and I tired loads of different things to get it working.... in the end I rebooted the S3 with a usb drive connected and it worked after that.
I'm on stock rooted LG6
This is what I got

yep, it is just a plug adapter.
You now have 2 choices:
1. cut open the micro USB, and connect pins 5 and six
2. buy one that actually says it is an OTG

USB OTG cable with charging - is that possible?

While researching ability to use USB DAC while charging the phone in the car I found this video. The guy clearly says that tablet is charging while accessing all those accessories via USB OTG. Similar cables are found on ebay, called "USB OTG with power".
The big question is: would the Galaxy S3 actually charge while using USB DAC at the same time? It should be possible, but I don't have the phone yet (still considering it), nor do I have the cable, nor a USB DAC In theory it should be the same with any accessory - can someone actually confirm either way, whether phone can or can't charge in USB OTG mode with similar cable? This video shows similar setup on Galaxy S (only it's normal OTG cable, USB hub, usb Y-cable and card reader) and it's definitely charging while mounting USB devices! Will S3 do the same?
I fear that upgrading from Galaxy S with voodoo control of Wolfson chip to north-American S3 with worse audio path might not suit me if there's no way to power the phone and use external DAC at the same time in the car... I hope there is a way... I appreciate any advice and opinions.
It's a first time I see such cable...All I read was people saying it's impossible in the first place. Well, hopefully in 2 weeks I'll be able answer your question

Looks like it's possible on some devices, but not with Galaxy and Nexus family... But it would be great if you can confirm that, so let me know if you can try it. Thanks.
Finally got the cable.
The result - nope, doesn't charge
Maybe the "Allshare hub" could do what your asking for?

Sonic, any luck with your friends phone? Really looking foward to your results :fingers-crossed:
Do you have part #s for the variable resistors in your samsung post or at least where you got them from? I would be willing to try some things out if I could find the right pieces. What I really want to get my hands on is the MHL adapter that was shown off with that spider laptop at IFA a couple weeks ago..
SUCCESS!!! I can confirm that this USB OTG cable (http://ebayitem.com/190710044655) DOES CHARGE MY GALAXY S3! I plugged in USB cardreader with SD card into the phone through this cable (it lit up and card is fully readable), then plugged USB cable end into PC and phone showed a charging icon! Moreover, after waiting for 5 min. with screen off (cardreader still glowing blue and working) battery has gone up from %72 to %75 (and while I was writing this, to 78%), so it is indeed charging! Yay! It probably won't get up in the car, where just phone alone is "not discharging" at best from the car adapter, but at least it should allow me to listen to music with quality DAC and use navigation without (or with minimal) discharging.
I have not tested it with USB DAC that I intend to use for my car (Behringer UCA222), because I have to go out and buy it. Hopefully it works. Anyway, this cable definitely works with simultaneously charging my north-american Samsung Galaxy S3 (from Bell Canada) while powering USB cardreader!
Somebody else has mentioned that another cable (http://ebayitem.com/120980364117) also worked in his Galaxy S2.
I bought Behringer UCA222 USB DAC and tested it in my car with the USB OTG cable with power that I mentioned. It works great! And the phone is indicating a charge. Sometimes when first playing music after plugging the device it sounds like fast forward for a few seconds (I guess clock rate mismatch or something similar), but after the presumably clock is locked it plays perfectly fine.

That is outstanding..gonna order one of these guys right now.
Here is a better link for all the ebay listings. Be aware of the differences, MicroUSB adapters would allow you to use your existing charge cable to plug into it while the standard USB would require you to be very close to the charger or have a USB A-A cable to attach to a power source.

The problem is that apparently not all of those cable work in terms of charging the phone. People say mostly that it doesn't work. The only guy mentioned success is with the cable I bought, but he then confirmed it with another, more convenient cable. I have the one that needs a USB extension cable to reach the charger, but it's about a buck on ebay, so no problem there. But not all cables work this way: most reportedly will allow you to power USB accessories but not charge the phone.
I found that this configuration works for charging while in USB HOST mode:
S3 -> standard otg cable -> Powered USB2.0 HUB -> devices (keyboard, usb dac, usb hdd...)
The only catch is that the hub must be powered before you plug in the phone or the phone will try to power the hub and will never enter charging mode. I'm using this setup in my car and it works perfectly. As long as I start the car before plugging the phone, we are good to go.
I only confirmed this works with AOKP JB builds. No idea about other roms/kernels. Hopefully this helps someone.

USB OTG + Charge?

I just recently got a Samsung Galaxy Note 10.1 and so far I'm quite happy with it --- except one thing, I cant find a cable that lets me charge the tablet *and* use the USB Host (OTG) port... (i.e. read files off a USB drive or play a game with a USB game pad while keeping the tablet plugged in)
Is there a way to do this? it would seem to me that all it needs is a splice to give power to the Power +/- pins on the connector while keeping the OTG Data +/- pins active...? (I know nothing about the pinout so I could be wrong on this)
Just to be clear I want to use the OTG adapter WHILE CHARGING (I've found one device that gives both these options but says "only one function may be used at a time")
Ideas?
Discussed dozen times in 10.1 forum. Actually it is not possible. Build an otg + power cable myself but it only works with timing and with a specific procedure... quite annoying. Wait for a custom rom somewhere in the future as I do.
You may have issues trying this, OTG cables are iffy under Jelly Bean. Some may work, some may not. In fact, Google removed references to OTG support for Nexus devices last November since OTG is so spotty. Splicing a cable that might work may kill it. Decent battery-powered USB and SD hubs are available and bypass the OTG problems. I have the RavPower RP WD01 and love it. The USB port will support drives upto 3T. It also has an SD card slot.

Powering the USB devices isn't a problem, I have a nice hub that powers them without issue, even extremely power-hungry devices. I was wanting to charge the tablet's battery while using the OTG adapter (original thought was for USB-gamepad-ing since high-requirement games drain battery, but I've since started using a PS3 controller over bluetooth so I can use the OEM charge cable and wireless for gaming --- but USB drives I'd have to copy the files over to internal flash or a MicroSD card to view while charging and i've found that the cards dont like files that are 8gb in size... (FAT-32 restriction iirc))

I saw that when I google'd but thought maybe there had been some new developments (especially with how this site's members love to tinker with electronics and write custom firmware). It's not a huge issue, since the Note 10.1 has amazing battery life (it's actually matching or doing BETTER than my iPad in most circumstances) I just like to never run the battery down low.. (why cant tablets have user-replaceable/swapable batters like most phones?!)
Thanks for the info!

Note 10.1 2014 OTG & Charging

I've got a Note 10.1 2014 mounted in the dash of my truck to replace the radio and am on a mission to figure out how to get USB OTG to work with charging. I've read an ocean of threads regarding hacking MHL adapters, but there is not any information specific to the Note 10.1 2014.
Right now I've got a relay system in the dash that switches between a OTG cable and a charge cable depending if the ignition is on or off. This works for my basic purposes, but if I use GPS navigation and wifi tethering, I run the battery pretty low after only 3-4 hours. When I turn off the truck it begins charging, but that wont work for a road trip.
I've tried the Samsung smart dock (without reading that it wouldn't work), and of course, it doesn't work, although it would be the perfect solution.
My idea is that there would be some way to use the 11 pin MHL connector on the device to get what I'm after. Looking at the pinout, it seems that there are some USB host pins within the 6 additional MHL pins, but I do not know of anyone who has tapped into them and had OTG working.
Is anyone else trying to get this to work on a Note 10.1 2014? I'm happy to hack up and solder anything and everything imaginable to give it a try, but I'd like to collaborate about it and see if we as a group can get this working.
Im about ready to rip apart my smartdock and see exactly why it wont work with this tablet.... have no idea why it qont recognise the tablet...

Man, you really gotta get us a screenie of this! That's bad ass.

Meanwhile, is there a possibility for that knock-out?
High current charging has an impact on the signal lines. So USB 2.0 current is limited to 500mA, or probably the 900mA from USB3, if the port can provide it. On a standard USB2 port the Note remains self-powered. And even with 900mA it will slowly discharge while in use, despite the battery charging at max current. On a 2A charger, the operating power bypasses the battery, which is much more healthy for it.
Thank you for your reply. Unfortunately I asked imprecise. What I liked to ask is, if there is meanwhile a possibility to charge the tablet while using the usb connection e.g. with an external hard disk?
Almost certainly not. Samsung could have provided a charger jack, or even support wireless charging. But it was not meant to be.
I just tried one of the charge and 2 female usb adapters off ebay and it didnt charge. It detected the usb connectors connection, but wouldnt charge.
$5 lost...
Did you used the wall plug? Because the tab needs 2A for charging...

Why not take away the USB requirement? I assume you want this to allow external storage, in this case get some sort of NAS that can be 12V powered and install that in your truck then allow the Note to connect to this via Wifi, then the USB port can be dedicated entirely for charging only.
Plus you have the benefit that when at home you can transfer file to your NAS without needing to leave you PC.

Are you using the LTE/3G for internet access? if not then setting up a wireless network in your truck might work. I use a HooToo TM001 (also have the TM002) to do this set up. The hub has a 6000mah battery that when the USB drive is not installed can charge a device.
i know it's been a while since OP posted, but i've been using a wireless HD so i can use external storage and maintain a charge. if you get the seagate wireless plus, you'll be able to charge and stream at the same time as long as you use a usb3.0 cable to charge from (it's included). using a 2.0 cable will turn off wifi.
it's quite a bit more than OTG, but it does allow you to have tons of storage available while still having a charging option.
I use a nexus 7 in the dash of my car (sure do wish I had space for the note 10.1 in there though!) With the nexus 7 I bought a y-cable that allows me to charge AND use otg functions. However, a specific kernel was needed im pretty sure. I set it all up a while back so I cant remember specifically sorry. Its all nexus 7 forums here though.

OnePlus 7 USB-C Dock Advice

I just received the phone and tried to use it with this dock with no results (the power led lights on and android P notifications shows the connection with a USB device, however it is not properly recognized).
I tried with an USB key, a mSD and with a HDMI cable attached. Any advice on alternative solutions? (both HW and SW).
I wish I could relate or let alone try to understand what you just said. I would have been fine with typos , but clearly your sentence structure is off even without proper punctuation. Regardless, thank you for the information sir.

Thanks for the tip Sir. I rewrote the sentences in a clearer way to make them easily understandable.
I was using a third party DASH cable originally for my OP3, with my OP7P and noticed it does the same thing as your dock. Side note the OP7P could not be recognized in fastboot with said third party DASH cable.
But the OEM cable works without fail ever time could be pin/or chip? configuration but I don't know enough about Warp/DASH/VOOC to say.

I made some further tests and these are the results:
- With the dock powered with a PD cable (so charging the phone as well) the video signal works as expected but no other devices are recognized (I tried a USB key, a keyboard and the usual microSD but none are visible)
- Using a simple USB-C to HDMI cable the video out works like a charm
I think the USB issue might be related to the drivers needed to identify the device (a similar situation happened to me on the Nexus 7 several years ago and I fixed it changing the kernel). For now I think I will have to find a different dock. The best one for my needs should have 2 USB, mSD slot, HDMI and Ethernet. Any tips?

One further update:
I used the same dock on the Mi A1 with Android P and it is properly recognized with both the mSD and the USB key attached. Obviously there is no HDMI out since the port is only a USB 2.0 one rather than a 3.1 like the OP7P.
At this point I think it might be related to drivers only, because the notification for an attached USB is there but it is not simply recognized (to be honest if i use the PD-USB while having the mSD inserted, the phone is charged but no popup for attached USB device is shown in that case).

Yeah I'm having the same issue, tried an HP dock and a Dell dock. Neither one supported USB. I don't understand why this is, never had this issue on older model Android phones. Must be the drivers.
FYI - The HP one displayed the picture on the monitor via HDMI, but wouldn't charge the phone. Dell one would charge, but wouldn't support the monitor. I have another model Dell dock that I'm going to try next week that I think will work better.
Another quick update.
All the test were performed with OTG on and with USB debug enabled and disabled to see if there are any differences in results(no differences for now)
Atzbee Dock
- HDMI Out working even without an external power source
- No USB drive/key detected
- Phone charging works
EC Technology Dock
- HDMI Out working even without an external power source
- No USB drive/key detected
- Phone charging works
So how can we escalate this to OnePlus? We should not be having these problems.
I made some further tests with several devices.
original OP OTG
Works with every device so far (not tested with Ethernet)
Vava 8 in 1 old & Vava 8 in 1 new
HDMI, USB flash, sd card and transflash work at the same time (even without an external power source).
I am finding problems in the connection of a keyboard or mouse that are never recognized (except for the original OTG cable)
Ethernet is never recognized.
To make sure before I buy one, the vava 8 in 1 hub works with usb flash drive while charging the phone?

Yes (on USB 3.0), however it is confirmed that is a limitation of the kernel, since flashing a different one seems to make everything work smoothly as reported here.

So it only works on a modified device? (unlocked bootloader, flash new kernel) stock does not work?

it works on USB .3.0 on hubs with stock kernel, but no keyboards or mouse (charging always worked for me). Modifying is needed to achieve the full functionality of the hub
You have to flash a custom kernel to get the USB type C keyboard and mouse working! Stock kernel does not work! Flash it and whalla! read my thread. https://forum.xda-developers.com/oneplus-7-pro/help/otg-usb-hub-recognizing-mouse-keyboard-t3936188
I just want to report that this issue has been resolved with Android 10. The HP dock I was using now supports the keyboard and mouse. Display and charging also still works.
Well that's a huge bummer, I regret buying the tmo variant. I reported this and chatted with one of the people there about pd+otg issues. I am able to get usb hubs to work if plugged into a c-typeA(f) adapter. That of course means no PD or HDMI, so it's awesome that Android 10 includes that fix!

Everything works, SD card, Ethernet, HDMI (Desktop mode or Mirror which one you want), Keyboard, Mouse, Flash drive. https://www.amazon.com/gp/aw/d/B07XRJDMLD?psc=1&ref=ppx_pop_mob_b_asin_title
