After reading this thread http://ubuntuforums.org/showthread.php?t=613758&page=2, the problem was solved for me. I suspect removing libsane-extras (and its according udev rules file) was the fix. I am not 100% sure though, as I did apt-get update just before rebooting now since I did not have time to look more closely into this. Also, removing libsane-extras using "apt-get remove" did not work, so I had to use dpkg --purge. FYI, YMMV.
