--- Comment #11 from Johannes Meixner <jsmeix@xxxxxxxxxx>  2007-09-13 03:34:58 MST ---
Attachment #163790 shows that the udev rules
in /etc/udev/rules.d/55-libsane.rules have been applied
because the group is set to "lp".

Attachment #163792 shows that the HAL/resmgr stuff was not done
because no ACL was set.

Because it works after re-plug, it shows that the HAL policy
files are correctly set up.
In particular your /etc/hal/fdi/policy/10osvendor/70-scanner.fdi
should contain this entry for your model:
-------------------------------------------------------------------
<match key="info.bus" string="usb_device">
 <match key="usb_device.vendor_id" int="0x04b8">
  <match key="usb_device.product_id" int="0x011b">
   <append key="info.capabilities" type="strlist">scanner</append>
  </match>
 </match>
</match>
-------------------------------------------------------------------

If the HAL/resmgr stuff works, getfacl would show something like
-------------------------------------------------------------------
# file: dev/bus/usb/003/003
# owner: root
# group: lp
user::rw-
user:<normal-user>:rw-
group::rw-
mask::rw-
other::r--
-------------------------------------------------------------------
to allow the <normal-user> read/write access.

As a workaround add the normal users which should be allowed
to access the scanner to the "lp" group.

I am no HAL/resmgr expert so that I cannot debug it further
and therefore I reassign it to the HAL maintainer.
