The lp group still (21.10) makes a difference for my combined printer and scanner. $ lsusb | grep Brother Bus 001 Device 004: ID 04f9:01ab Brother Industries, Ltd MFC-240C $ ls -l /dev/bus/usb/001/004 crw-rw-r-- 1 root lp 189, 3 mar 12 11:01 /dev/bus/usb/001/004 > If you remove yourself from both of those groups, does this stop > working?

"scanimage -L" keeps working without the lp group (also without sudo) but apparently there is more into it. ** Attachment added: "simple-scan_error.png" https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1890464/+attachment/5568207/+files/simple-scan_error.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to sane-backends in Ubuntu. https://bugs.launchpad.net/bugs/1890464 Title: Can not scan as user Status in sane-backends package in Ubuntu: Confirmed Bug description: # Description I can not scan as user using software like simple-scan or xsane.
