This is the answer i received few days before you can also find it in the archives : Possibly the problem is the USB device node, /proc/bus/usb/$BUS/$DEVICE only having write permissions for root. If you do a sane-find-scanner, you'll get a line somewhat like this: found USB scanner (vendor=0x05d8, product=0x4003, chip=GT-6816) at libusb:001:002 The two last numbers are the interesting ones: in my case, $BUS is 001 and $DEVICE is 002. My scanner's device node is /proc/bus/usb/001/002, which by default was owned by root with permissions of 644. I solved this by creating a symlink from /dev/scanner to /proc/bus/usb/001/002. Then when I login at the console, /proc/bus/usb/001/002 is chowned to james and chmodded to 600. Now I can scan as a normal user.
