Hi list Scenario: FC1 Mustek BearPaw 1200 CU flatbed scanner (GT-6801) USB copied firmware to /usr/local/share/sane/gt68xx/PS1fw.usb 'chmod'ed PS1fw.usb to 755 commented out override in /etc/sane.d/gt86xx.conf When running XScanning I get (even as root): Failed to open device 'gt68xx:/dev/usb/scanner0': Invalid argument Opening Kooka (bottom left panel): Problem: no scanner was found. scanimage -L picks up the scanner. sane-find-scanner also picks up the scanner. Hmmm... what am I mising? Thanks in advance. Stuart
