I took the scanner, SCSI-2 cable, and acard SCSI host adapter and
plugged them into my roomate's windows computer, installed the
appropriate drivers, rebooted a few times, suffered through windows'
occult complaints but eventually got the device functioning.
Next I tried it on his FC4 system (same hardware, different OS) which,
upon loading the appropriate kernel modules segfaulted the kernel and
froze the machine.
Sometimes I am able to get the kernel modules loaded on my machine
before the atp870u driver complains. At this point sane-find-scanner
detects the scanner
found SCSI processor "HP C2520A 3644" at /dev/sg1
but `scanimage -L` does nothing. Perhaps it precipitates an error of
some kind because after cancelling the command sane-find-scanner again
detects nothing and subsequent driver reloadings print out the same set
of SCSI errors.
I know at lease someone somewhere has gotten this scanner working before
because http://www.sane-project.org/sane-mfgs.html says that support for
'ScanJet 6100C' is 'Complete'.
What can I try next? I'm willing to start hacking hardware/drivers if
necessary but I have absolutely no idea where to begin, nor even where
