Please see the "SETUP" section of /usr/share/libsane1/doc/README.Debian.gz. You must either be logged into a physical console on the system (not an SSH/VNC session) - or if you want to bypass that requirement, you must add the user to the "scanner" group. This is expected behavior.
(Adding the user to the "lp" group happens to work because your device is also a printer - but that's technically not the right answer for scanning.)
If this issue occurs when you are _physically_ logged in, please change the status back to Confirmed.
