Thank you for your reply, may I get hold on your code please?
Thanks,

I'm trying to implement simple USB device in u-boot for at91rm9200 and
as a first step I want to see that I can work with interrupts there. I
added temporary device initialization code to usb_lowlevel_init():
I used the USB Device port as a console for my at91sam9261, acting as a usbser.sys compatible usb-to-serial port. It was a lot easier to use a polling interface because there was some Atmel sample code available.
During early startup, I add the usb driver with device_register(). Each function polls the status register, which works out fine since uboot calls tstc constantly to look for a new character or putc to display something. Finally I added a check for the device sense (power) to skip the initialization completely if we know it's not connected to anything.
