Per AlbertoP "to access the scanner, for example via "YaST scanner setup" ->
"Other" -> "Scanning via Network" -> "Local Host Configuration"

Adding this fixed the problem with being unable to scan with user priviledges.









Reproducible: Always

Steps to Reproduce:
1. Hook up HP Laserjet All-In-One 3030 using USB cable
2. Install hplip, hplip-hpijs, cups, xsane or skanlite
3. Try to install printer in HP-Tool box (No printers detected)
4. Able to install printer in CUP since opened using root
5. open xsane of skanlite with user privileges, error "No devices detected"
Actual Results:  
open xsane of skanlite, error "No devices detected"

Expected Results:  
Opened program and detected scanner

This is an old issue, which was fixed long ago and appeared again! :-)

Looks like a duplicate of the current bug #542473:
  "HAL does not set ACL for normal user access
   for devices with 'scanner' capability"

See there how to check if this one is really a duplicate.

By the way:
This kind of HAL issue usually re-appears again
for each Suse Linux / openSUSE version and
must be fixed again and again, compare bug #438867.

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.

It seems you did run the report of hp-check at
http://pastebin.com/m1e93c4f7
as normal user so that it doesn't show the numerical UDB IDs of your
hp:/usb/hp_LaserJet_3030?serial=00CNBM186335
device (all USB devices /dev/bus/usb/*/* have "Permission denied")
but I would need the numerical UDB IDs to check
if your device is listed in
/etc/udev/rules.d/55-hpmud.rules
and in
/usr/share/hal/fdi/information/20thirdparty/70-hpmud.fdi
