Avasys Image Scan included with OpenSuse10 works properly for my scsi Epson 1640SU/ADF as root user only, both from a terminal and as plugin from Gimp 2.2. Here is what happends starting Image Scan in a terminal as normal user: ~> /usr/bin/iscan An "Iscan" message box pops up: "Could not send command to the scanner. Check the scanner's status." <OK> The problem looks to be that the access rights to my scanner /dev/sg0 is limited to root only, while my scsi cdrw drive is set "correctly to my user".
lsscsi [1:0:2:0] process EPSON Perfection1640 1.03 - [1:0:3:0] cd/dvd YAMAHA CRW4416S 1.0g /dev/sr0 terje@dhcppc2:~> ls -la /dev/s?0 crw-r----- 1 root disk 21, 0 2005-10-17 01:32 /dev/sg0 brw-rw----+ 1 terje disk 11, 0 2005-10-17 01:32 /dev/sr0
Trying to change owner on /dev/sg0 to my user works temporarily, so that I can start iscan without being root. The problem with this however, is that after rebooting, the system sets the owner back to root again. To compare, Ubuntu 5.10/Gnome has this user setting: * System>Admin>Users and Groups -> User rights in my user's properties shows that -> Use Scanner Devices is schecked 1) How is the corresponding scanner access user right set in OpenSuse10? 2) I also have a related user rihts problem using /opt/"appsdir" to download rpms. Even if I set chmod to 775 and chgrp to users, after a reboot the system has removed the users rights, and I cannot longer save the download files as a normal user as I wish. Is there some way to keep this setting? 3) In Solaris there was a group "sysadmin" with access rights between normal "users" and "root". Is there some similar group to add in OpenSuse10/Linux?

/etc/init.d/sane-dev would do it automatically if it is enabled and if the scanner can be found during booting (i.e. when the scanner is switched on during booting and when "scanimage -L" detects it).
