It works only for all-in-one devices where a scanner is included and when the scanner unit was set up with YaST. It does not work out-of-the box for a plain printer. In the past I fooled myself by testing it with my HP LaserJet 1220 which has a scanner unit. > > I have HPLIP 2.7.7 running on a AMD 64-bit (X86-64) machine > > using openSUSE 10.3 (beta2) with a HP DeskJet 3320c USB printer. > > I am running 2.7.7 (from your home repository) on an AMD x86_64 with > openSUSE 10.2 with a PSC2175. > > By default it is > > > > [EMAIL PROTECTED] lsusb > > Bus 002 Device 003: ID 03f0:7004 Hewlett-Packard DeskJet 3320c > > [EMAIL PROTECTED]:~> lsusb > Bus 004 Device 002: ID 03f0:2b11 Hewlett-Packard > > > [EMAIL PROTECTED] ls -l /dev/bus/usb/002/003 > > crw-rw-r-- 1 root lp 189, 130 2007-09-13 15:55 /dev/bus/usb/002/003 > > [EMAIL PROTECTED]:~> ls -l /dev/bus/usb/004/002 > crw-rw-r--+ 1 root lp 189, 385 2007-09-14 06:27 /dev/bus/usb/004/002 Note the '+' which indicates the ACL set via HAL/resmgr because of the scanner unit which grants access for the user who is locally logged in (i.e. via "console"/XDM/KDM).

If I had a list of USB product IDs for all HPLIP supported devices, I could create a matching /etc/hal/fdi/policy/10osvendor/70-hplip.fdi file to grant the access out-of-the box for HPLIP devices even without the need to do the permission stuff via YaST for HP all-in-one devices. If there was a list of USB product IDs for all HPLIP supported devices, even the udev rules would be correct and would no longer set HPLIP permissions for any HP USB device. In particular no longer read access for all users for a HP USB mass storage device or a HP USB keyboard. (If any user can read the keyboard, any user may be able to read the keystrokes e.g. when the login password is typed.)
