As for BeOS, I started porting libusb some time ago, and got some help 
on it but it's still not working fully, so I'd rather keep the BeOS 
code in for this release if possible...
even if it uses the usb_scanner driver which serves no purpose but 
publishing /dev/scanner/usb/* from an hardcoded list and have a vendor 
and device getter ioctls... I wanted to recode that to use the usb_raw 
driver through /dev/bus/usb/ to avoid hardcoding the list of scanners 
more than once in sane itself, but I suppose it'd be simpler to just 
use libusb when it's working.

Haiku doesn't have a usb_scanner driver anyway so libusb will be the 
way to go then when it's ready.
