Comment 25 for bug 121082

Thanks, hedgefighter! Adding both udev rules, in the two different files as you describe, worked for me too. (And wow, is this scanner crappy. I think I'll keep my old Epson running.) I guess the key is that the rule has to be in /etc/udev/rules.d/45-libsane.rules, not in /lib/udev/rules.d/40-libsane.rules.

Anyone know the difference between /etc/udev/rules.d and /lib/udev/rules.d? Why do they both exist?
