The group id for the scanner device should be 'lp', but there should be
a read/write ACL entry for 'scanner', and there isn't. The "udevadm
test" output showed that it should have tried to make one, but
apparently that didn't happen for some reason. Try running as root
setfacl -m g:scanner:rw /dev/bus/usb/002/006
getfacl /dev/bus/usb/002/006
or whatever the devname currently is. If it shows a line like
group:scanner:rw-
then the problem is that udev isn't running setfacl for some reason or
that it is failing due to something different in its environment. If
it produces an error, then that's probably the cause.
I ran the two commands and both return without error. The latter
(getfacl) returns the following:
getfacl: Removing leading '/' from absolute path names
# file: dev/bus/usb/002/005
# owner: root
# group: lp
user::rw-
group::rw-
group:scanner:rw-
mask::rw-
other::r--
Thanks
