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?

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?
