Which version of sane-backends (scanimage --version)? > I am using Snapscan with firmware u176v046.bin. Sane is located in > /usr/share/sane and I have an entry for the scanner in /dev/usb/scanner0. At least with current versions of the snapscan backend, you don't need to specify a fixed location of the scanner device in snapscan.conf (but its vendor/product ids): usb 0x04a5 0x20b0 > Everything works ok but if I unplug the scanner, either the power or the > USB, then when I try to start Xscan again it can't find the *device*.

I.e. does cat /proc/bus/usb/devices list it? Is it found by sane-find-scanner? What is printed in syslog (/var/log/messages) when the scanner is unplugged and plugged in again? I have two ideas about that problem: a) The scanner is detected again after the replugging, but as /dev/usb/scanner1. or b) The kernel scanner module crashes for some reason and doesn't detect you scanner again. That can happen when you unmplug your scanner while scanning an image. Bye, Henning
