I tried to connect some devices via usb.
The Adaptercable is working because I tried it on a different phone andit works.
But no devices seams to be recognized. I tried
an usb stick (even works on an old glaxaxy s3)
a dvb-t device .. not working
a usb mouse .. nothing
my usb midi keyboard.. nothing.. not even the light goes on.. (on my Jiayu S3 it works with the same adapter )
any ideas?
kind regards

I tried to pair wired mouse, wireless mouse and a gamepad with OTG cable and even with mini-USB to USB.

Issue 22038: USB OTG doesn't work at all.
ICS supports it but the Galaxy Nexus does not. there is a mod in the development section that allows USB devices to work.
you mean this:

Hi,
I'm trying to use a USB Keyboard with my Archos 80 G9.
First of all, I did the Softwareupdate ( 3.2.80 ) but no Keyboard or other USB Device (USB Stick, Mouse) worked. I'm Using the USB Port at the back ( the one for 3G Stick ).
So I flased the "old" Firmware (3.2.79). After this USB Sticks work fine. But still no Support for the Keyboard.
Did I did something wrong (3G is on)
Does it work with you guys? If yes what Firmware do you use?
Thanks a lot and best regards

Try using USB hub, it's possible that tablet doesn't use hardware that declares more power usage than USB port can give (all USB devices declare max current draw during the handshake)

You need an Micro-USB-B-OTG-Adapter.
Try www.adaptare-shop.de and search for OTG (or amazon etc.)

Rear USB working with mac keyboard
Ok, so what gives? The rear usb works with a mac keyboard......I can even make a cheap leather cover/usb keyboard (ebay special) work IF I plug it into the Apple keyboard. Thoughts? Suggestions? I'm guessing there is something going on with the grounding on the Apple keyboard.
Have you tried turning the 3G stick on under Settings?
I believe that power to the back USB port is off until the 3G stick is turned on.
Don.
Hey! So i managed my S2 to work with an OTG adapter. Now it recognizes Flash drives, USB mouse and keyboard as well. My problem is though, that i'd want to use both the mouse and the keyboard simultaneously, and later on my tablet as well.
I've got a USB hub which was pretty cheap i guess,
ht tp://itmedia.sk/item-images/other-usb_omega_hub4portSTARpowercapable/it6818_2.jpeg?nc=032
When i connect it to the OTG adapter it lights up, and if there's a flash drive attached to it when i plug it in, the phone recognizes the flashdrive without problem. As soon as i plug in a second flash drive, the light goes off from the HUB and both of the sticks get unrecognized. Also, the mouse nor the keyboard works through the HUB somehow..
I need to buy a specific hub with OTG support or a power hub perhaps? Could anyone help in this? I looked over google and stuff but people seemed to say different stuff at almost every site.. Thanks!!

Oh well that's quite interesting. Then you're saying this piece of video could be fake perhaps?
Since i can post links yet, search for this on youtube: USB HUB Support On GALAXY S2
Check the very first video.
I'm convinced that the every phone can handle only one device connected at the same time.

Well, it surely doesn't seem that way, that's why i was asking, since it's possible.
Weird.... i got sgs2 and 4-port usb hub and when i connect 2 pendrives to hub and hub to phone everything works good (i see UsbDriveA and UsbDriveB). If your hub have dc input you can try connecting power supply to this hub. Maybe this hub isn't compatibile with your phone.
So Ive run into a strange problem. I was watching a movie last night on my nexus, the file was on my usb drive connected via otg to the nexus. Today I try to do the same and I get no reaction from Stickmount when plugging in the drive. I have no problems charging or connecting the tablet to my PC, and the drive works fine both connecting to the PC and to my smartphone with stickmount as well. I also tried DLing an app called OTG Troubleshooter to see if that would help me. When connecting the drive it tells me that OTG is detected, but that "Mass storage USB device is not detected in linux/android". Does anyone know what the problem is?
Thanks in advance
Nexus Media Importer
I had a similar problem with the device not recognizing the OTG cable, it went away after I installed the Nexus Media Importer.

I tried with Nexus Media Importer as well, no success there either, it doesnt detect the drive. Thanks for the tip anyway
mine does the same thing with both stickmount and nexus media importer, I even tried 3 different OTG cables and flashdrives and get the same results

I have the same problem and have just tested that connecting a mouse or keyboard to the otg works without problems, what doesnt work is a flash drive. ( I have tried different flash drives to no success)
Does anyone know what the problem might be?

I uninstalled and then reinstalled it again and now it is working again. I think it might have been slow to update
Maybe you guys are using a Kernel with OTG+Charge option? if yes the problem maybe that you have to connect the AC charger and USB device together. If you don't need the OTG+charge you should deactivate that function.
After upgrading to lollipop OTG doesn't seem to work any more
I stick a multi SD / USB adapter and it doesn't do anything
should i enable something? like developer menu?
I have the same problem

Works fine for me on my 10.5, maybe you have the wrong otg cable?
Do you see the notification in the status bar when connecting a device.
no notification, but with same cable and same USB pen connected to Samsung S6 it works
not sure why and how it worked but connecting tablet to PC, it was recognized as external storage on mac with android app
now after disconnecting OTG works

I am having same problems as others. Tried al404's suggestion in various forms and still nothing. The problem may be unique to the Wifi only models. Does al404 have LTE? I also have loaded various ROMs, including Liquidsmooth (which supposedly had OTG control), and they have not helped.
