In the subject you've mentioned /dev/ulpt (USB LPT port), and now /dev/lpt (conventional LPT port), still the same applies for both. > Why? Because the content of /dev is dynamically generated and maintained as a virtual file system. This service is controled by devfs (devices created at startup time) and devd (devices dynamically created during runtime), both with their respective configuration files devfs.conf and devfs.rules, and devd.conf. Those files need to be adjusted. To make the change become active, restart the service. > What did I do wrong? You did not use the current proper method. :-) Make the change you need in /etc/devfs.conf, e. g. perm ulpt0 0664 if you need rw/rw/r. You can also use "own user:group" in a similar way if you need to change file owner or group. See "man devfs.conf" for details. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
