Access rights became the following: -rw-r--r-- 1 root root 80 2009-02-21 15:10 /proc/bus/usb/001/003 crw-rw-r-- 1 root scanner 189, 2 2009-02-21 15:10 /dev/bus/usb/001/003 But 'scanimage -L' still didn't work (neither under user nor under root). By chance I found out that if I first change directory to /usr/local/etc/sane.d, scanimage works: $ cd /usr/local/etc/sane.d $ scanimage -L device `pixma:04A926B4_SDF760260809Q' is a CANON Canon imageCLASS MF4010 multi-function peripheral $ scanimage -T scanimage: scanning image of size 640x877 pixels at 24 bits/pixel scanimage: acquiring RGB frame, 8 bits/sample scanimage: reading one scanline, 1920 bytes...
