Hmmm, why 0664?

Either grant access to anybody or RW-Access to owner and group
(root:operator).

perm	uscanner0	660

Interesting idea to apply devfs rules from devd ...

But the following does work as well and is a less heavy weight
solution:

# The entry below grants group operator access when a scanner is plugged in.
attach 100 {
	device-name "uscanner[0-9]+";
	action "chmod 660 /dev/$device-name";
};


In fact, the default permissions of uscanner devices might be too strict
and the best fix might be to have the mode default to 0660 (root:operator).
