I think I found a solution for the problem in comment #5:
I will add the access permission test also to
/usr/lib/YaST2/bin/test_scanner_backend
which is run when clicking [Test] in yast2-scanner.
Then the workflow is as follows:
1)
The full automated USB scanner setup via udev
activates the matching scanner driver but it cannot do
an access permissions test as described in comment #5
2)
If access permissions are sufficient (the normal case)
the user can use his scanner out-of-the-box.
3)
If access permissions are not sufficient,
the user cannot use the scanner and because of this
he runs the YaST scanner setup module.
4)
The YaST scanner setup module runs as root and therefore
it can access the the scanner and reports it as "configured".
Now the user hopefully finds the "Other" -> "Test" function.
Because root can access the the scanner, the actual scanning test
will be successful but the new additional access permissions test
would notice insufficient permissions for normal users so that
YaST can report an appropriate message to the user to inform him
what is actually wrong.
