I found a problem in the hiddev driver causing it to get corrupt as soon as it 
sees a usb reset comming from user space.

The usb reset is used for DFU (device firmware upgrade) and therefore 
perfectly legal in this case, though i understand that it is unusual, and 
might have not been tried therefore, earlier.

The problem can be reproduced very easily and reliably using the related 
libusb function and can cause kernel oopses or plainly a driver not working 
anymore in the best case.

The good news is that many other drivers i'm running here happily survive this 
"attack".

I'm willing to go after the issue but would prefere to do this with anyone who 
takes care of the driver anyway.
