Hi people,

I have one question regarding sane-"backendname" user permissions. Whenever I need to use my scanner (model HP PSC 1310), I have to start it from the console, because it's asking me to enter the user password.
Code: 
% xsane
Password of user on localhost?

I added the following related variables in /etc/rc.conf:
Code: 
dbus_enable="YES"
hald_enable="YES"
cupsd_enable="YES"
devd_enable="YES"
devfs_system_ruleset="devfsrules_common"

I have established in /etc/devfs.rules:
Code: 
[devfsrules_common=7]
add path 'ugen[0-9]*' mode 666 group operator
add path 'usb/*' mode 666 group operator
add path 'usbctl' mode 666 group operator

My user belongs to the cups group. All works fine, except the user's password requirement which is very annoying.

Does someone know how to avoid having to enter the user's password, every time I use xsane?

Yes, it is. If you need more information, please, let me know. I'm not sure if I missing something else :\

Thanks for your time, @wblock.

Try adding your user to the lp group if not already a member. I believe I had to do that a while back when I had the same printer (before it died) to scan without a user password. I cant remember for certain however, and I don't remember why. Sorry, I should have kept notes.

xsane should not involve CUPS at all. My /etc/devfs.rules does not have a usbctl entry.

You're right and I'm most likely not remembering correctly. Sorry for the noise.
 
Re: Trouble with SANE and USB scanner

First, I want to give thanks to all people who try to help me with this annoying issue :)

I performed some changes which I will describe below. Second, I deleted this line from /etc/devfs.rules
Code: 
add path 'usbctl' mode 666 group operator
I added my user as member of the lp group, but I had not success. Unfortunately, xsane still requesting for a password.
Code: 
% pw group show lp
lp:*:1002:root,charly
Does anyone have a clue?
 
Re: Trouble with SANE and USB scanner

Please do that again, but for the operator group. And ls -lh /dev/usb*. And the entry in the config file for that scanner in /usr/local/etc/sane.d/....

My scanner uses an external backend which it's included in the HPLIP software. See this link for more details.
