But if that is the problem, then please explain why I can scan as root but not as ordinary user? When I create a link uscanner0 -> ugen0 that link gets permissions lrwxr-xr-x and I can't change those. I then run as normal user $ sane-find-scanner -q found USB scanner (UNKNOWN vendor and product) at device /dev/uscanner0 found USB scanner (vendor=3D0x04b8 [EPSON], product=3D0x0121 [EPSON Scanner= ]) at libusb:/dev/usb0:/dev/ugen0 So you see, it's not that I can't find the scanner. It is beyond me to understand why sane-find-scanner works as documented but scanimage don't. According to documentation this scanner uses the snapscan backend, in snapscan.conf I have: firmware /usr/local/etc/sane.d/Esfw41.bin # If not automatically found you may manually specify a device name. # For USB scanners also specify bus=3Dusb, e.g. # /dev/usb/scanner0 bus=3Dusb #/dev/uscanner0 bus=3Dusb usb /dev/uscanner0 I have tried specifying the usb-scanner, both as written in the handbook and as suggested in the file and without any entries. No change. I don't think this file is read, because that would probably require that scanimage first identify the backend.
