>    - USB support (needs fixing)

Hi,

If questions arise I can answer them and give advice with regard to libusb in 
baseport and the USB FS interface. I've been somewhat involved fixing the USB 
support for VirtualBox under FreeBSD last time, and I think the VirtualBox 
team did a minor mistake from the beginning and that was to use the USB FS 
IOCTL interface directly, instead of using the USB library from baseport. 
Anyway, that works too as long as you understand a bit of USB :-)

Currently there are some issues. One of them is that certain functionality is 
only available as root, like detaching kernel drivers and such. I'm not sure 
what the best way forward is. Currently PRIV_DRIVER is used for alot in USB, 
and VirtualBox needs that to function properly currently with regard to USB.
