Hello,
Can you have USB OTG and phone charging at the same time? Or even better: HDMI + USB OTG + charging? Without power the phone discharges fast, not to mention - with HDMI out connected I won't be able to connect external HD with movies... Oh, bother...
Or is there some magic do-it-all dongle?
I need it too .
I hate some cable in my bag. One Cable for all is great
USB OTG does not support charging as it has to supply current to the external device.
MHL (HDMI output) does.
Dude, I really hope I'm not misunderstanding, but what is the problem to which 'USB OTG and charging at the same time' is the solution?
Surely you pop your USB stick in, transfer the file and then... stick the charger/HDMI cable back in... and stream wirelessly/over your network?
What were you hoping to achieve? There are several options...
Just taking a guess... maybe he wants to use keyboard and mouse etc with his phone, desktop style

Or maybe I just want to play anything from my 1TB HD WITHOUT deciding what should I copy to my phone (which is a waste of time...)

I wanted to do the same thing but it isn't possible . I do however stream from my nas if I don't want to copy stuff to the phone.
Technically, the USB-OTG standard includes provisions for handling this.
There are several occasions where you would want to plug an accessory into a USB-OTG port and still be able to hold the state-of-charge in the host device.
The specific document: Battery Charging Specification, rev 1.2
ACA subsection (Accessory Charger Adapter)
The ID_OTG pin acts as an input in this mode of operating, indicating whether or not the host is allowed to charge.
Figure 6-6 shows the typical architecture.
Sounds promising. I will look into that! Thanx.
Any news on this?? :fingers-crossed:
so can we use otg and mhl at the same time without charging
Yes, this is pretty much possible. I have implemented the aforementioned OTG ACA support and got it to CyanogenMod9 upstream. Anything which uses the same kernel (or, if you can cherry-pick changes and compile your own kernels), could use that too. Changeset URL: _ttp://review.cyanogenmod.com/#/c/15850/
You need to use a regular USB OTG cable, but place a 36 KOhm resistor between ID pin and GND, then you should connect GND and Vdd to some power source. I used an MHL adapter which I had no use for, as it had two of three connectors I needed. This setup allows me to watch movies from 2.5" notebook hard drive while simultaneously charging my phone if I plug in a 2A-rated adapter. Note that it's impossible to use 650mA charging rate due to chip restrictions (USB HC is too stupid to understand the direction of current flow, and it reports an over-current condition); you have to settle on 450mA.
If you don't know how to solder, or if you use something else than CyanogenMod9 and cannot compile your own kernels, you are out of luck.
I have tried to find an existing USB OTG ACA dongle, but I was not able to find any. If you will be more lucky than me, you can just use it--my patch is compliant with USB specification and will support any compatible dongle.
It's possible.
You need cable y usb. I did it myself.

What specific parts did you use for your OTG / Power Y
The ability to charge my device while playing video off a usb flashdrive is my goal for this.

Duh, I read right past this post... 36KOhm on ID <<< got it, now to experiment!
wow!
it would be amazing if such a device existed!
Hello,
I'm new to this forum as i didn't need it yet but now I have a question.
I know this thread is kind of old and I'm not sure if there are still (m)any people using a GT-I9100... though it would be interesting if anyone found a solution on this topic.
I read several threads where people were discussion if charging and OTG is possible at the same time but no one could verify a specific resistor. Actually i tried a resistor valued 124k between GND and ID but it didn't work. I also read about 36k and other values but nothing verified. Could take a while to try several resistors but i really no one knows a solution i'd try this
So just so sum up, i don't need "MHL and charging" or "audio out and charging". The mode i'm looking for is "OTG and charging".
My Goal: a Docking Station with mouse, keyboard, flash drive(s) and charging to remote control my computer with a software like splashtop.
Hopefully anyone has useful information on this, thanks a lot for any kind of support

Thanks for your answer!
Today i made my 36k cable, this weekend i should have some time for the kernel patch - hopefully
I still have some questions about the kernel as i didn't use any custom ROMs etc on my phone. All I have is a "standard" root kernel without any further changes but root. Need some hours to read into this. What i didn't understand: Do I have to use a specific CM9 or can i use any CM9 (or maybe CM10 or any other CM past 9)?
I wasn't able to get the link working "_ttp://review.cyanogenmod.com/#/c/15850/" when replacing "_" with "h". What can I find on that page?
Just that, if anybody can try this out would, it would be awesome. You can follow the steps in this article:
http://www.xda-developers.com/android/determine-your-phones-usb-host-capabilities-with-usb-host-diagnostics/
I will make the test myself when I have the phone, but, I live in Argentina so, It'll take a while, I'll be making the payment trough PayPal probably next Monday, soo, that'll be 5 days for the package to be delivered to my courrier's office in Miami, next, another 3 business days for it to be delivered to my partner's house in Chile, and, with luck, another 2 or 3 days till my partner pick it up and bring it to Argentina for me XD

Thanks ! Sounds good to me, Device detected it's gonna be always no, if nothing it's plugged, so that's OK, and, if the Kernel claims support, I'm pretty sure it'll work, after all, this is "Kind" of a Galaxy SII device.
Are you saying that if this works we will be able to plug in a USB Key or an SDCARD via a dongle and upload files to and from our phone. Wow that would be crazy useful. Imagine plugging your friends android phone in USB mode and transferring some files to him.
If we have USB Host anybody thought about this:

I have the OTG cable and it works great. I've tested it with a Flash Drive, Mouse, Keyboard, even showed a co-worker how I could charge his iPhone with my phone. Haha
I did the test for you and attached a screenshot of the results.
Wow! That is cool, how did the mouse work? Do you see a mouse in android? Did the keyboard work well? With the flash drive you get to see the files on it?

Yes, a mouse is displayed on the screen. It works great, right click acts like the back button, scroll click like the menu button, left click acts like your finger touching the screen (including drag, click and hold). The keyboard is similar with certain keys acting like the android buttons. Also, you can view and transfer files to and from your flash drive.
It works just like it does on the SGS2, tons of videos on YouTube. It's an awesome feature!

Wow I can't wait to try this.....Now, how would I use an MHL cable and a USB mouse and Keyboard.... Kind of would turn my phone into a PC if I could do that. Lets see a Micro USB to USB Hub. Plug into the hub the Peripherals then plug the MHL to a Micro USB to USB converter and away I go....Of course power the MHL. I don't think the MHL connector would like to go behind a USB hub though. In theory is this not what the docking station is doing in order to run the Ubuntu on android? OK not with this phone but on the one that they are demoing it on.

It's a lot simpler than that, just use this MHL cable:
http://www.samsungcaptivateglideaccessories.com/capigpitalsdfkzlig-11.html
Just plug it to your phone MicroUSB port, then plug a MiniHDMI Cable to the MiniHDMI port of the MHL cable, then plug that MiniHDMI cable to your Monitor/TV, on the other side, plug your phone's MicroUSB cable into the Female MicroUSB port of the MHL cable, and then plug that USB cable to a Hub, then just plug every other peripheral into the Hub, and of curse, if you're going to use an External Drive or something like that, remember to buy a 9V/12V AC Adapter for the USB Hub.

So your saying to plug the MHL adapter to the phone and to plug the Hub to the MHL device. I do not know if this will work as you need to Power the MHL adapter. Are you saying that powering the hub will power the hub and the MHL adapter? Have you tried this? I have the MHL adapter and I love the HDMI ability of my phone but I found I can not use to long a HDMI cable as it will not work since the HDMI cable is drawing power from the MHL adapter. 3 Feet works and 10 feet does not. I have not tested others in between yet. Oh and yes I do power the MHL adapter via another device (USB port to Power, or a Battery device to MicroUSB)

I have tried using the MHL and USB OTG cables at the same time and had no luck. Didn't attempt with any powered USB hubs.
What I have done is use the MHL adapter, and a bluetooth mouse and keyboard at the same time. Similar to video here, http://www.youtube.com/watch?v=uEb-DICYCgg.

I bought a generic MHL cable online and couldn't get it to work; but got it working with two other phones. So apparently you do have to buy the special Captivate Glide cable. Can anyone verify this? I'd hate to pay extra for another cable that didn't work
What did you have to do to get your MHL Cable to work?
It does look like there are several different ones, so I'll try ordering another one...

He is talking about OTG Cable, not MHL Cable, no one has confirm that the MHL Cable works with the Glide, only way to know for sure, it's buying an Original Captivate Glide MHL Cable, that most likely it's the same one that for all the Galaxy S II variants out there

I bought my MHL cable at Monoprice.com for cheap and it works great with a 3Foot HDMI cable and powering the MHL connector.
THe only reason we are talking about the MHL and USB cable is because you need both working to really use the phone on a screen with a USB mouse and keyboard. I ordered a cheap USB host to Microsub cable on ebay when it comes from China I will let you know if it works with and without the MHL.

Did they work together?
Works for me sort of...
My micro usb port is loose & i have to hold the phone & cable tightly together to get it to connect. Because of this i can no longer charge my phone directly & have to charge spare batteries separately & swap when they run down.
I can also confirm the hdmi out works too & i have a bluetooth mouse that connects nicely at the same time for remote control.
Wished they would have used a usb mini instead of micro, as the micros tend to fail after moderate use.

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.

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!

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,

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)

I use one of these.
Found this to be the only proper answer since powering a mouse, keyboard and a external hard disk with OTG would murder the device battery in seconds.
But this works.. i have not gotten around a electronics shop to grab a 100K resistor to test if that solves the charging issue yet but i will keep you posted as soon as i can get to a 100K
I'm using a standard $60 11,000mAh portable charger as well. Works fine powering my keyboard and mouse with the OTG Y cable.
I think this thread should be in the accessories subforum
should be mentioned that to use the otg with external power system on our need to modify the kernel to support it by one ...

I'm using this with a Y cable for OTG with f4k kernel. Works perfectly fine.

USB-C to USB-A OTG Cable -
Not able to power a simple external USB MSata Drive or External USB HDD - I plug these drives into a LG V10 or a Galaxy S8 and work perfectly fine. What gives? I have only able to get a flash drive to work.
Any known work a rounds? Anyone else try this?
Thanks,
No answers for this?

I tried this just now and am shocked it doesn't work either.
I wonder if OTG power support was removed due to the decrease in battery size? Has anyone tried OTG "audio output", say through a device like the audioquest dragonfly, to see if that works??

I don't think so, since the notification that pops up when I connect 32 GB ADATA USB 3.0 flash drive -> USB 2.0 A female to micro-B male OTG cable -> micro-B female to USB-C male adapter -> Z2F says the Z2F is providing power to the connected device. The problem is you can't do anything else BUT that.

I'm wondering this myself. The fact that the Z2F outputs analog audio over USB-C leads to me to believe that it isn't fully USB-compliant.* Both the HTC U11 and Google Pixel 2 output digital audio, which, based on Google's crowing about USB-PD and the existence of devices like the dragonfly, appears to be the right way to do things (albeit with the tradeoff of more expensive audio peripherals, which much now have their own onboard decoding hardware.)
*Can anyone with knowledge of the USB spec comment on this?
BTW, I started a support thread about this at the official forum, where it's received several replies and suggestions from a mod. Kindly chime in there too so Lenovo can see this is a real issue they need to address.

So based on this Motorola mod post and the OP's statement that USB-C flash drives work, the Z2F and Z have the same (lack of? LOL) OTG functionality. The Moto Z subreddit has a pretty extensive thread about Moto Z DAC functionality; it appears the Dragonfly is supported, among others.

Interesting development: another Motorola Forms mod now says powered USB hubs are rumored to work. We're making progress, folks.
Okay fellas,
I so far have been able to get certain drives to work and others not! I have tried 2 different USB-C to USB-A cables and get the same results, 1st ones an HP cable and 2nds an Anker USB-C to USB 3.1 Adapter
https://www.amazon.com/gp/product/B01COOQIKU/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
I have been able to get a 256gb M2Sata Drive, 500gb WD Mypassport, and a 2TB Mypassport to read.
I also have a 256gb MSata Drive that will not power up or read without using a powered usb hub. However the Msata Drive will read without an added powered HUB. On the Samsung and LG Devices.
Only thing I can think of is that certain drives have higher amperage that the Moto Z2 simply cannot push through its USB-C Port.
Good to know it isn't just me experiencing broken USB OTG support.
I've got a PS3, PS4, and Xbox one controller I hook up with USB OTG. Normally it's as simple as plug n play and I'm good to go. However, that doesn't seem to be the case here. I can still pair the PS3/4 controllers in sixaxis just fine and get power to the PS3/4 and Xbox one controllers. And yes, that bit about supply power to device rather than transfer and you can't pick something else, happens to me too. Sometimes I can plug my thumb drive in and I can explore through the storage file explorer, but I usually have better luck with an app called X-Plore.
This one time I even had said thumb drive take out my entire OS to the point where I had to use that June ROM to reset me back to start. Spoiler alert: I kept getting "Android.process.acore keeps crashing" over and over; various other apps kept crashing as well.
On a side note if I can at least get PS3/4 controllers to work for a long time within say, sixaxis (or similar) I'd appreciate any tips. Otherwise I either gotta wait for this to be solved in a future upgrade, future sixaxis, or when we start getting custom ROMs..

This is excellent information, thanks a lot man.
So FYI I tried the Anker adapter @XE-Cherokee linked to and it worked perfectly. That seems to be the solution for now.

Appreciate the heads up, to confirm this adapter works perfect with my external drives, and as an added plus, also my external DAP/amps for audio playback.

The latest Neutron and USB Audio Player Pro will output bitperfect (non upsampled) audio perfectly to both my portable DAC/amp units.
USB Audio Player pro, has the benefit that you can stream tidal native, bitperfect if you have an acct. Which is awesome imo. Tidal still buffers SUPER slow on this device though. So I'd recommended only offline use (which you CANT do with USB audio player pro due to licensing)
I would also add that I get some scratchiness out of the stock USB C to 3.5mm dongle that came with the phone. I thought it was the port being "dirty",. but I have NO NOISE out of the USB audio output using the Anker otg cable. Maybe Anker makes a USB c to 3.5mm adapter.
One tip for getting USB powered OTG drives to work is to use as short a USB cable as possible. Like get a good quality 1ft USB cable. I used to have a similar problem with using an external drive on a Wii and found that a 1ft cable would allow me to use 2 different drives that otherwise would not work with a 6ft cable.
It worked!
I used a USB 2.0/type C adapter that cames with s8 and instead the original USB 3.0 cable, put another adapter, and transferred files with Total Commander.
On this subject but kinda off topic. How are you all getting your drives mounted? I cannot mount NTFS or fat32 drives. Only ext3/4 drives.

Yep, basically you created a 2 inch cable. LOL.
In essence, many USB powered hard drives approach the power limit of what the USB port can output. Power drops over the length of a USB cable, so longer cables may not provide sufficient power for the drive to function correctly. Better quality cables usually have less power drop, though it is not a guarantee.
Unfortunately most USB powered drives do not list their power requirements. The only way to really tell is to open the case for the USB drive and look at the hard drive inside it to find how many amps it draws. For the best compatibility you want the lowest amps.
I don't think that's otg power issue. I think it is locked by Moto becuase they want you to use their add-on devices. I have a wifi camera it doesn't work either, But it works in my all other phones

Just because an add-on device works for one USB OTG implementation doesn't mean that it works on all USB OTG implementations. There is an enumeration of what devices and types are accepted. I have tested USB OTG audio microphones, USB OTG audio speakers, USB OTG Headphones, USB OTG Ethernet, USB OTG Keyboards, USB OTG Flash drives and those device types work. If there is no device driver for the device attached then it would need to be supplied by an app. OTG power drain is definitely an issue and is mentioned in the OTG specifications.
That's what I tried to say. It is locked by Moto. They want you to use their add-on mod. I have tried extrenal usb c endoscope camera, wifi endoscope camera, lg wireleas projector, Samsung projector. None of them work with Moto. However, the same apps work in all other phones. It is clear to see, it is not all otg related all the time or driver which provided by app. It could be just locked by Moto, becuase they want use to use their mod add-on. People who rooted the phone was able to turn on those supports.
I use a Belkin OTG adapter, it worked but it was extremely picky. The Built in files app only picked up my HDD if it was either Fat32 or exfat. But the ES File Explorer app only picked up NTFS.
