The problem is that the printer appears as ugenXXX.Y, but other usb
devices (disk, usb-key, ...) also have an entry in /dev/ugen/

You really don't want to allow the users to access these devices, but
*only* the printer. This is why we use a devd rule that test the type
of the device. I don't think we can do this with devfs.

And the ugen number differs if the usb port is not always the same.

Regards.
