Nontheless, my /dev/lpt0 node still only has permissions set to 0644.
In the subject you've mentioned /dev/ulpt (USB LPT port), and
now /dev/lpt (conventional LPT port), still the same applies
for both.
Actually, the standard devfs.conf settings do not work for dynamic
devices like ulpt0. devd is the only way to do that for dynamic
devices. Here's an example I use use for a USB printer. The vendor and
product IDs were determined with usbconfig dump_device_desc:
# WB
# link Epson R200 printer to /dev/ulpt-r200 and unlpt-r200
attach 20 {
device-name "ulpt[0-9]";
match "vendor" "0x04b8";
match "product" "0x0005";
action "ln -sf /dev/$device-name /dev/ulpt-r200";
action "ln -sf /dev/`echo $device-name \
| sed -e 's/ulpt/unlpt/'` /dev/unlpt-r200";
action "chmod g+w /dev/ulpt-r200 /dev/unlpt-r200";
};
# WB
detach 20 {
device-name "ugen[0-9].[0-9]";
match "vendor" "0x04b8";
match "product" "0x0005";
action "rm -f /dev/ulpt-r200 /dev/unlpt-r200";
};

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, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Is this about /dev/ulpt[0-9]+ or about /dev/lpt[0-2]? If the latter is the case, then maybe you should edit /etc/devfs.conf instead.
