musb in devkit8000 board


I am testing Devkit 8000 board.

I am loading the default kernel comes with the board.

I am using OTG mode. When i connect usb keyboard and mouse, there is no interrupt or no response from usb.

Is there additional to be done to make usb work in devkit 8000.

whenever i connect or disconnect, no messages appear in dmesg, it is idle.
How to debug ??

Thanks and Regards,
