thanks a lot for the great work! I'll commit the patches soon.
One thing I noticed already is that resetting an USB device from a normal user account is not possible with that code.
The best approach to fix that is to implement a kernel driver included in VBox which implements the missing
functionality imho. We have a USB support kernel driver for every supported host except Linux (and now FreeBSD)
for this and to properly support USB filters to prevent another driver from capturing the device.
