Although there is usb interrupt request in Interrupt Controller, I can't
know what the interrupt request is coming because UDC Status/Interrupt
register returns 0.
My problems is..
1. USB interrupt occurs continuously.
2. But USB register bit correspond to the interrupt is not set.
This is so weird.
Thanks.
