USB OTG not working S2 - Galaxy S II Q&A, Help & Troubleshooting

Hi. Today I tried to connect a flash drive, a mouse and a keyboard but none of them worked. I saw videos on YouTube showing that you only have to connect the cable and that's it. No apps of configs. When I connect the OTG cable it detects it and a notification appears saying USB connector connected. The flash drive's LED flashes and even the mouse optical flashes red but nothing happens. No cursor and no drives in memory. What can this problem be?
I am using Siyah's Kernel V6b4 and have JB 4.1.2 official leak.
Thanks for your help!!

I'm on Xylon ROM (trinity kernel) on galaxy nexus. I bought an OTG cable to play Vice City on my GN. No notification here, I test a mouse successfully but my Xbox controller doesn't work.

But I have Galaxy S2. And on some videos on youtube even with stock firmware 2.3.4 it worked.

I noticed that on the videos the notification is "USB host connected" while mine says "USB connector connected".
My OTG cable has a short between pin 4 and pin 5. 5 volts are coming out because I tested it with a multimeter.

It's mostly up to the kernel to provide OTG support. And unfortunately it seems it usually isn't something the kernel devs prioritize. I've had pretty good results with the CyanogenMod stock kernel though.

Can I install only the kernel on 4.1.2 leak? Because cyanogenmod does not support MHL and I don't wish to flash it.

[Q] Hooking up a USB keyboard to a Nook Tablet

It is my understanding that android natively supports usb. My question is, if I get a micro usb to usb adapter, and then plug in a usb keyboard, I would be able to use the keyboard to type documents. Any thoughts?
(I have a rooted nook, but I got the update before I could block them, will revert back soon)
currently no. The android or in this case nook skinned android kernel has to support usb host and usb keyboard inputs which it doesn't. But it probably will in the future when the devs release android 4.0, because ICS needs a different kernel then the current nook tablet kernel. But anyway what keyboard do you have, because you can only connect bluetooth keyboards and also only if the developers can enable bluetooth on the nook.
It also depends on the hardware support. I don't know if the TI chip has a host-only port, or if it supports OTG (On-The-Go) dual mode operation. It probably does, but I've not seen anybody verify that.
it doesn't support USB keyboards. I have a female USB to micro USB for my galaxy S2. I tried to get a USB sick and 2.4GHz mouse and keyboard on the nook but nothing worked, and yes it both works on my galaxy with the stock ROM

The NT can support usb gadgets and usb hubs but it need to be enabled in the rom and the must have the module, the NC has this feature and i hope our great devs can implement this on the NT.

im looking to use a usb 3g modem myself with my tablet ,
ive read a bit on the latest engadget article about the other older e paper nook that was done with a usb keyboard i even went as far as to contact the guy who did it and he told me what to look for , hardware wise to see if the NT could do it ,
yet without kernel support or the module being compiled into the kernel we have already on the tablet , theres not much hope , but i believe it can and will be done , if not im gonna have to get an ipad with a 3g data card in it cause i have to have data access wifi hotspots just not cutting it..

USB OTG - supported usb wired ethernet

Hi Folks,
I have the OTG cable and USB Y cable working my touchpad with 7/30 CM9 nightly... I would like to purchase a USB wired ethernet adapter. Has anyone tried and know of one that would actually work on the touchpad with CM9?
Thanks a ton!!
Anything that Android 4.0 supports should work unless its limited by our kernel. I'd say there is a good chance this one would work as it mentions plug and play compatibility on Android 3.2+. But there could be kernel limitations so you may want to get another opinion.

[Q:] CM9 Nightlies no go w/ S3 (I9300) HDTV Adapter (EPL-3FHU...)?

Hi guys, could need some help, please:
I just can't get a picture from my S3 (neither YouTube, Homescreen, nor movie from SD Card) to show on my LG HDTV's screen... Any idea, why?
Just in case you're wondering...
-- I do have the latest/correct Adapter for the S3 (Model code: EPL-3FHUBEGSTD/Original Samsung bought on Amazon)
-- I have connected the S3 charger to the Adapter
-- One side plugged into HDTV, the other into the Adapter, and the latter plugged into S3.
I think that the CM9 Nightlies (RC2) just might not be up to par... (??)
Can anyone confirm it's actually working with your International S3 (I9300) and XpLoDWiLD's version of CM9 ??

I can confirm this on the Cm10 nightlies.
The mhl adapter works fine on Samsung-derived Roms, just not the CM ones.
I wonder if a different kernel would help? I plan to try a few later...

i have this exact same adapter and can confirm it working perfectly fine on samsung roms. I have posted a similar thread on getting it to work with USB OTG here: http://forum.xda-developers.com/showthread.php?t=1836822
I believe there must be something in the kernel to enable HDMI output (seeing as i get a "HDMI cable connected" notification) as well as switching into USB Host mode (and thus providing the adapter with power). It has been suggested that among the 11 Pins in the new Galaxy S3 port there should be 2 separate USB Ports, one to be used for charging, syncing, data cable, MHL, etc, and one to use for USB OTG while the other is in MHL mode.
I am hoping for new insight into this matter, since this would empower the device greatly. Together with the superior hardware, this would definitely be a killer feature.

USB OTB with Charging

Anyone known of/if there will be a kernel or ROM that will enable USB OTG and charging? I have that set up for my Nexus 7 and would really like it running on my HOX+ I'm running the NAM version.

I am noticing at least nominal USB OTG support on my AT&T HOX+ with stock kernel. Just tested a wireless mouse and flash drive and both work just fine. As for "charging", I'm unsure of what that entails, but unless one of the kernels in the Development forums mentions it, you can expect that it's not currently on anyone's todo list.

Nexus 9 - no otg support?!

Hello good people,
I was so happy, that i can use Nex9 like Linux Desktop, because i used Nex7 (2012) like that.
Bigger screen, bigger experience. So i happily bought USB OTG, connect and....nothing.
Tried mouse, keyboard, two kind of OTG cables, HDD, two kind of Flash Disk's their formats etc...
I tried everything rooted, unrooted from 5.0 to 6.0.
Can u help me or explain me the situation?
Thank you sweet devs (no homo)
Still hoping.
Adam
Did you tried different USB OTG adapter? I tried pc mice, 3 USB sticks, 3TB HDD and everything works, no root stock Nexus 9

it works just fine, so its something you are doing or have on the device or ......
I just tested with a USB flash drive and my Audio DAC, and both work great.
Did you find a solution? im having a similar problem with my Nexus 9, it recognises the USB but NOTHING plays back, i just get play back errors.
Im using a USB OTG cable with a 32gb flash drive, both Nexus media importer and other file explorers display the contents but nothing plays back at all
SOLVED!

Hi! Yes, i solved this. Upgrading to 6.X (CM) it was first thing that works for diagnostic. Second thing is the OTG cabel. YOu have to use special OTG with electronic. (i personally call it expensive and cheap OTG) . Thats it. I hope that i helped you. Because i was very sad in your situation.
Sorry for english. I am from Bananastan
