Scanimage shows my SCSI-2 Umax PowerLook 2100XL still functions, after asking about it a few weeks ago with no reply. However, SANE does not make it usable. It worked on earlier Slackware with the same SCSI card in a different PC. The successful test was from an old sane-devel thread (from 2006, 'UMax PowerLook 2100XL under OpenBSD, still') about someone with the same sort of problem (same scanner & error, but on OpenBSD). Below is the output from the failed test, and then the syntax of the test that worked, and what people in the old thread thought the problem was.
root at cosmos:~# scanimage -d umax:/dev/scanner --format pnm > outfile.pnm scanimage: sane_start: Out of memory scanimage: received signal 15 scanimage: trying to stop scanner However, I have 64 GB RAM, and almost 2 TB free in my /home/user folder, of which, in the 2006 thread, low space was suspected to be the problem, as was a SCSI buffer size setting. The following test produced an image. scanimage -v --resolution=300 -y 100 -x 100 > test1.pnm 2>debug.txt I do not recall changing a SCSI buffer before; it is not something I know much about. Can anyone tell me if that was it and what to do or read? I also commented out all other backends, and I do not recall if I was supposed to edit something in the umax backend configuration. On earlier Slackware, I recall maybe doing so or just making sure umax was in the main sane configuration and drivers were loaded (I loaded sg, but the successful test did not need the aic7xxx old or new driver for my SCSI card, so I suppose something else handles it, though perhaps the problem is the test ran with another, not quite adequate driver).
