Hi, first you should find out why the Plustek backend refuses to work! There are at least two points: - make sure that the backend can access the scanner device - make sure to have appropriate device entries in the plustek-devs.c file
Then also decide how to access the scanner: sane-find-scanner says libusb:001:005 but you tried to use /dev/usb/scanner0 this does not work!!! - unload scanner.o - patch the plustek.conf file, use only the following entry: [usb] device auto This should help so far... If not: try export SANE_DEBUG_PLUSTEK=12 ; scanimage -L and send us the output for further analysis Cheers Gerhard On Dienstag, 18.
