Scanner permissions again - only root works

I have a SCSI scanner Hewlett-Packard ScanJet 4c. YAST sees it as Hewlett-Packard SCSI processor ‘C2520A 3503’ at /dev/sg3 but ends saying “The following models are not known to HAL: SCSI-device=/dev/sg3”
I cannot make it to understand that it is a good old ScanJet 4c which should be well supported. It works of course but I have to use it with root privileges.:
[2:0:0:0] disk ATA Maxtor 6L160P0 BAH4 /dev/sda
[2:0:1:0] disk ATA IBM-DTLA-307015 TX2O /dev/sdb
[3:0:0:0] cd/dvd HL-DT-ST DVDRAM GSA-4163B A104 /dev/sr0
[5:0:1:0] process HP C2520A 3503 -

that has been a perennial problem with us too: only root has access to the scanner; each version of Gnome?? seems to have that; our KDE install of 10.3 did not bring that issue:

I currently do


and then as su

chmod a+rw /dev/bus/usb/00*/00*

according to the entry for the scanner

then I can run xsane

what do you do?

I spent some time reading about various entries I could make in files; all to no avail for me; I do get a sense it is a Suse speciality; other distros do not seem to specialise in it

As my scanner is not an usb device it doesn’t show on lsusb list.

I have just changed to OpenSuSE from Ubuntu. There I had the same problem and started xsane with “sudo xsane”.

I guess with SuSE I have to use it as root but as I seldom use the scanner, it is not such a big thing :expressionless:

I found with my mother’s HP F4280 all-in-one printer, for her to be able to user the scanner, I had to add her user to group “lp”. I then restarted the PC and she could use the scanner as a regular user.
