That's the problem :-) The backend doesn't use the kernel USB scanner driver as far as i know, but it uses libusb. > Judging from one web site that I have found, this might be expected behavior, > but then why doesn't sane-find-scanners work? sane-find-scanner only finds USB scanners if they are detected by the Linux kernel driver.

Two problems come to mind: 1) libusb only works as root AFAIK, so if you run xsane as user... 2) Maybe xsane finds an old SANE installation without sm3600 support? > sane-find-scanners doesn't list any scanners. That's ok in this case. That's one of the reason for the "some" in the sane-find-scanner output: "some scanners that are connected to the Universal Serial Bus". > I'm running Linux 2.4.27 Cool :-) >, Debian (unstable/sid).

Check if there is an older sane-backends installed from debian. I don't remeber exactly, the name of the package maybe libsane or similar. Bye, Henning
