Yes. I use a scanner and I don't have to add anything special to my OS 
configuration. I just start Simple Scan, and the application detects the 
scanner. My user is not in the "scanner" group.

But the scanner works like this only recently. Before, I had to follow these 
instructions: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=38064#11

Also, check that all cables are plugged properly.
