Interrupt handling - USB root port

NTDEV
1

Hi,
I have one usb device. i have enabled registers in the driver function
EvtStartHardware. But when i do this, at the time of driver loading , i get
“usb root port” interrupt. I cleared it by writing 1 to it. But still
interrupt does not get cleared. Do i need to process something more in order
to clear the “usb root port” interrupt?

Please guide me.

Regards,
Shalaka

Do you mean the usb root port interrupt for your wireluess usb controller? If yes, go read the wusb spec again?

Thanks for update.
I had again gone through WUSB spec and i got it. It is used in connection
establishment process. Hope, i am on right track.
