[sane-devel] ScanJet 4C

[Ted Parks]

Yes, I did reboot after changing the scanner's id.=20

I don't have a SCSI terminator on the other connector coming out of the 4C.=
 How important is a terminator? From my Mac days, I think I remember using =
unterminated SCSI devices without any problem.

Thanks,
Ted
