OTG doesn't work

---

I tried to pair wired mouse, wireless mouse and a gamepad with OTG cable and even with mini-USB to USB.
Nothng's working and it doesn't even read it.

Any ideas why and what should I do?

see
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:

?

unlocked he bootloader, rooed my nexus, flashed recovery and flashed this kernel and still no support for usb devices...

any way google will support it in the nexus in the future?
