[vbox-dev] [PATCH] VirtualBox USB support under FreeBSD 8/9+

[Alexander Eichner]

Hi,

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.

Regards,
Alexander Eichner
