Users from group scanner/saned are not able to see/use scanners on 18.04
I moved old scanner hardware to Ubuntu 18.04 and noticed that regular users are not able to see/use USB scanners.
Running:
scanimage -L
returns empty scanner list, while running:
sudo scanimage -L
shows scanners present.
I tried to follow
https:/
I had to add extre udev rule:
/lib/udev/
with:
ENV{libsane_
to have scanners working.
Is it Ubuntu bug, feature?
If feature how regular users are supposed to work with usb scanners?
TIA, regards,

Above two entries are identified as scanners (libsane_matched) by udev, so now they have g:scanner:rw.
In original Ubuntu there ware without ACLs set.
2nd entry is multi functional printer, so it has lp group set by udev.
what is the output of:
groups
Please?
