Okay, so with that information combined with the dmesg output you
provided earlier (not quoted above), it's safe to say the problem here
is that your scanner is not recognised by uscanner(4), and needs code
written or USB device IDs added to the list to get support for it.
Devices which aren't recognised often show up as ugen(4) devices.

This thread should definitely be moved to freebsd-usb.
