hey guys
i recently got a USB otg cable for my S2(GT-I9100) and while this cable fine works with pen drives it doesn't work with any USB Keyboards or Mice that i plug into it. every time i do plug a keyboard or mouse, the phone completely freezes and i need to do a restart to get it running again

but still no good
any help will be appreciated
(PS: i am running siyah kernel 2.6.12 along with android 2.3.6)

Same here Bro
Heyho XDA,
sorry for pushing this old Thread,
but i have exactly the same Problem
Everytime i plug in a USB keyboard or a mice,
the Phone freezes instantly -.-
My Setup is:
CheckRom Revo v6
Siyah Kernel v2.6.13
Original Samsung OTG cable
Anyone else having this issue?
Or maybe a fix ?

Same problem
I've got the same problem. Pendrives, memorycardreader and systemcamera works great, but no mouse and keyboard.
Tested the same setup on my friends Galaxy Note and it worked out of the box. But not on my phone.

Download
USB Host Controller from the Play Store , see if that works.

It seems that USB Host and USB OTG are two different things. It has to be supported in the kernel. And I did root my phone and derooted by changing the kernel. I didn't save my original kernel so I had to download a new one. So maybe my kernel doesn't support OTG anymore.
I'm gonna look closer into this and report back it I'm getting it to work.

USB mouse issue.

In the last days I flashed my P7510 from stock HC 3.2 to CM10 4.1.2 and it all seemed much faster.
But with the stock HC, maybe thanks to something Samsung installed in the stock rom, as I plugged a usb mouse to the tab (using the usb otg samsung adapter) it worked at once and a mouse pointer appeared in the screen.
After the JB update the mouse would not work.
Is there something I need to enable in the settings or any app do I need to install to use a usb mouse?
Would it work if I bought a blouetooth mouse instead?
Thanks.
No one has ever tried using a mouse?

[Q] OTG strange problem

Hello all,
first of all, tried to use search of this problem, couldn't find anything.
So my problem is that when I connect to my GT-I9100 OTG cable with flash drive(8gb) it just dosen't detect it also tried using philz, apollo(dosen't remember corectly name) dosen't work either. Tried using OTG Troubleshooter it is question mark on "OTG Detected", with OTG cable everything is good because asked my friends to use it, they said that it worked for them. I thought it was my phone usb(where you put in) was damaged but no, phone is charging perfect also USB to PC works correctly. Also OTG cable holding very weak.
My rom:Neat rom(newest)
Kernel: Dorimanx(newest)
Thanks for help
Merry Christmas and happy new year

USB On The go, yes or no?

Hi,
I have been looking for a long time, but it seems the desire 601 doesnt support USB OTG? Can someone confirm a running OTG on it?
I just bought a cable for it, and tried a couple of USB pen or mice on it without success at all. The mice led even dont start blinking once it is connected.
I might be the board of the 601 doenst supplie the power for it?
thanks

It supports OTG, I have tried connecting a mouse, keyboard, gamepad, usb sticks (fat32, you need an app to mount other filesystems) etc. and everything worked.

Great, do I need something to install? Or must the ROM be rooted? I just have the original rom installed no root.
thanks

If the usb stick is formatted as fat32, then you dont have to do anything. But if it is ntfs or other fs, you should install an app like stickmount, which requires root.
And for mice and keyboards, no other app is required, it works out of the box.
Hi,
do you have any custom rom running on it? I just have the stock rom which is even rooted, but no mice or stick is workin, but even no led appears, which acutally should blink once a usb pen is plugged, or not?
thanks

[Q] Please Help! USB OTG Not Working on Blackview Ultra A6

So I tried using OTG devices with the Blackview Ultra with both the stock rom and CyanogenMod 12.1 installed but it just doesn't work. I have tried multiple USB OTG cables and none have worked, I know it is not the cable because it works fine with my friends phone. I have also run USB Host Diagnostics on the phone and it says that the OS supports OTG but simply no device is detected.
The bizarre thing is that the Ultra itself claims OTG support. It even comes with an OTG cable included in the box!
So if anyone could give me some insight on this it would be greatly appreciated. I really want to see some USB devices working with my phone. Thank you!
Bump
Anyone?

Q1:
Have you tried connecting your device to the computer via a USB cable? Can the computer recognize it?
If no, maybe there is problem with your USB port.
If yes, proceed to the next question.
Q2:
Have you tried changing the connectivity state for the USB port in Settings?
If not, try it out now.
If yes, report back and we'll discuss further more.
Use Es File Explorer... That's what I've been using
Sorry for late reply, I got it working, I replaced the usb cable, I think that the quality of the cable was too bad
