SANE can either use the kernel scanner driver (uscanner on FreeBSD) or
generic access methods with libusb. That's /dev/ugen* on FreeBSD, I
think. As uscanner has evry limited functionality on FreeBSD, libusb
is the better option.

To get more detailed debug output, disable everything but plustek in
dll.conf and set SANE_DEBUG_SANEI_USB=255 in addition to
SANE_DEBUG_PLUSTEK. "scanimage -L" should show more details now.
