Ok. > PLEASE, any help would be appreciated - I've been working on this for weeks! See above. Have you checked if you don't use two different installations of SANE? E.g. check sane-find-scanner: ldd /usr/bin/sane-find-scanner Check libsane: ldd /usr/lib/libsane.so.1 And to be safe, check the plustek backend: ldd /usr/lib/sane/libsane-plustek.so.1 Also check if scanimage is linked to the right sane-backend libs: ldd /usr/bin/scanimage You may need to adjust the paths. All should print something about libusb. If sane-find-scanner is linked to libusb and libsane isn't, better ask your distributer what the heck they are doing. Bye, Henning

Note that sane-find-scanner DOES find the scanner (using libusb), but scanimage does not. PLEASE, any help would be appreciated - I've been working on this for weeks! Lloyd Sumpter
