I'd say this could come from udev and its rules because a default Debian
install adds your user to the "scanner" group (you can view the groups
you pertain by running "id").
If you are already on that group but still cannot scan with your user,
check if there's any rule created for your device and if so, put here the
line of reference. If there's none, maybe is that you have to add a new
one :-?
