There is a firmware file, and the upload "just works" under FreeBSD 7.x and earlier.
I have this in /usr/local/etc/sane.d/snapscan.conf:
firmware /usr/local/share/sane/snapscan/SnapScan_1212U_2_Scanwise_2.00.bin

This is already in snapscan.conf:
# Agfa 1212U
usb 0x06bd 0x0001
usb 0x06bd 0x2061

The last one is the id; why there are two lines I don't know.

Doesn't work for mine:
root at kg-v2# scanimage -d snapscan > /tmp/test.pnm
scanimage: open of device snapscan failed: Invalid argument
root at kg-v2# scanimage -v -d snapscan > /tmp/test.pnm
scanimage: open of device snapscan failed: Invalid argument

root at kg-v2# scanimage -L

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

Goiod idea, but that wasn't the case.

I agree; flatbed scanners are cheap. However; I have this unit already taking up some space here,
it works with earlier versions of FreeBSD, so I would prefer that I could get it working
with FreeBSD 8 as well.
