Default Printer dont take rights

Hello,

I try to deal with my usb printer but I dont understand why it dont works as I set it.

I set in devfs.conf :

perm ulpt0 0666
perm ulpt1 0666

But when I connect the printer what I get is :

ls -l /dev/ulpt0

crw-r--r-- 1 root operator 0, 138 4 oct 11:36 /dev/ulpt0

and I have to set manually with root :

chmod 0666 /dev/ulpt0

ls -l /dev/ulpt0

crw-rw-rw- 1 root operator 0, 138 4 oct 11:36 /dev/ulpt0

to enable printing with any account.

I guess it's could be related that printer not connect at system start but connected later but what's wrong ?

/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)

Thanks and shame on me for not reading the man once again
In fact I used it to add permissions for CD writer and then just add the permissions for the printer while not even reading the man when it didn't worked ...

And it may also be the answer to your other problem. Many printer drivers reset the device at various times, and this often leads to the device being redetected and assigned default permissions.
