I know some C, but very little on USB architecture.  I'm curious enough 
to try, but a bit more direction would be helpful if you can spare some. :)

BTW, is this behaviour BIOS related?  I recently setup another machine 
that had Intel's Z77 USB3 controller, and I don't remember having these 
issues when attaching the same USB3 device...


Thanks,
Aragon
