The user access ACL entry is missing. That explains why your ordinary
user cannot access the device. (I assume that udev and systemd work fine
on your machine, or have you noticed issues that might be relevant?)
Do I need to chown bobg here? It looks like it ought to work as
is for bobg with 664 ownership?
That won't survive a reboot, and when removing+readding the device the
problem would reappear.
Do you run with SELinux enabled and enforcing?
Yes
Do you get denials in /var/log/audit/audit.log? (it could be that XFCE
doesn't run the SELinux troubleshooter, so you would not learn about
SELinux problems)
I don't get any SELinux warnings but then I don't know if that
function is working either. The log data is overwhelming! I see
nothing that seems to pertain to "sane." But I could have missed
it ... I tried checking the end of the log immediately after
xsane errored, saw nothing I recognized as a problem, but would I?
What happens if you switch to "permissive mode" temporarily (either
at boot time) or by running "setenforce 0" as root, then plug in the
scanner?
Did that, unplug scanner, run setenforce 0, plug in scanner and
try "xsane" again, same error, device not available. Is there a
command to verify it's actually switched to permissive? There's
so much to know!
Is there something I need to enable under "Users and Groups"
possibly? I looked there but didn't see anything I recognized as
applicable?
