/etc/devfs.conf is only used at boot time or when devfs is restarted, the first few lines of the
devfs.conf(5) manpage say this. If you have a USB printer that you are plugging in after boot time, you should use
/etc/devfs.rules. Very basically, you could add to it:
Code:
[system=10]
add path 'ulpt*' mode 0666
Then add to
/etc/rc.conf:
Code:
devfs_system_ruleset="system"
It might be a better idea to make the mode 0660 and assign a printers group, but that's up to you. Also, you will either have to reboot after this change, or add the ruleset manually.
See the following manpages for more details:
devfs.rules(5),
devfs(8)
