Comment 1 Johannes Meixner 2009-12-18 15:47:10 UTC

It looks like a duplicate of bug #542473
("HAL does not set ACL for normal user access
  for USB devices with "scanner" capability")
See there how to check if this one is really a duplicate.

The best workaround to get those kind of HAL issues
out of sight is to use the YaST scanner module and:
-----------------------------------------------------------
.. you could access
the scanner via the 'saned' as a workaround.
For this workaround choose 'scanning via network'
and select the 'local host configuration'.
----------------------------------------------------------
In particular on a workstation in a trusted network
environment (e.g. when the Suse firewall protects it
from acceess from the external network zone / Internet)
this workaround should cause no security problems.


Alternatively - and to get additionally even the device status
information via hp-toolbox working:

In particular on a workstation in a trusted network
environment (e.g. when the Suse firewall protects it
from acceess from the external network zone / Internet)
you may change as a workaround in /etc/udev/rules.d/55-hpmud.rules
in the line (which is only here shown wrapped):

ATTR{idVendor}=="03f0", ATTR{idProduct}=="??17", OWNER="root",
  GROUP="lp", MODE="664", ENV{sane_hpaio}="yes"

the MODE="664" to MODE="666" to allow any user read/write access.

According to /usr/share/hplip/data/models/models.dat
the USB IDs for a HP LaserJet 3030 are 03f0:1617
so that the above line in /etc/udev/rules.d/55-hpmud.rules
should be the right one for your device.
Check the actual USB IDs whit the output of "lsusb"
(you may have to run it as root).

Thank you, the 'saned' workaround with 'local host configuration' brings back the expected functionality.
