In scanners section:
By default, under 5.X, uscanner0 permissions are 0640 preventing users in operator group to use the scanner (a write access is required). So let's show how to change the permissions to 660 (for example) via devfs.rules and the devfs_system_ruleset option in rc.conf. This gives an example on how to change permissions on a node that is not always present at system boot.
