I'm just guessing: The backend tries to identify the scanner (vendor
and product) and gets the response that this is not possible (FreeBSD
uscanner driver can't do it). Usually that's no problem but the
umax1220u backend seems to insist on this identification.
There is a line
in the code (backend/umax1220u-common.c). Try
and recompile. Maybe that's enough to get it running.
Probably the maintainer of this backend can tell more details.
You may also try the CVS version of sane-backends which has support for
libusb. This may work (if you have installed libusb).
Otherwise I guess the backend must be changed.
