In the meantime (without doing anything): /usr/local/bin/scanimage -L device `pixma:04A91908' is a CANON Canoscan 9000F multi-function peripheral It works as user too, after changing /lib/udev/rules.d/40-libsane.rules > We should add something like the description below to README.linux.

After reading your explanations I don't understand, why scanimage recognizes the scanner after some time / days without doing anything? I don't see a permission problem in this case (since I did nothing) or something changes the permissions automatically. I compiled with default values. While it didn't work for a while with Ubuntu 12.04, it works now without problems, as I described in my earlier mail. BTW I have a Nikon LS50 too. How do I compile drivers for the Canon 9000F and the Nikon LS50, but not the other drivers? How must I change: BACKENDS="pixma" ./configure -- ?l
