oh, my fault- its already in sane. but as the manpage says, it only
supports the Mustek BearPaw 2448 TA Pro. So unless this machine is
identical, you will have to do some hacking: for starters, this
backend has a hardcoded usb VID and PID, so you will have to rebuild
the backend from source to even try it.
1. download sane source
2. look in backend/mustek_usb2_asic.c for ProductID and VendorID, and
change those to match your machine.
3. configure
4. make
5. make install

If you need pointers on these, let us know. we cant be sure of your
experience level.

Unfortunately, even after all that, there is a good chance it wont work.
