I've booted Ubuntu 14.04.5 from the LiveUSB prepared using: dd if=ubuntu-14.04.5-desktop-amd64.iso of=/dev/sdX bs=4M and couldn't reproduce the problem with my 1212U.
In case of openSUSE a very similar problem has appeared to be caused by the tlp package (and its /usr/lib/udev/tlp-usb-udev bash script). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to sane-backends in Ubuntu. https://bugs.launchpad.net/bugs/1532582 Title: Regression: SnapScan 1212U stuck after scanning one page Status in sane-backends package in Ubuntu: Expired Bug description: If I scan a page using the Agfa SnapScan 1212u, the scanner bar does not return to the edge but stops in the middle of the scanner at which point the scanner powers off. If one now tries to do another scan, the motor give a squeeking sound for some seconds without movement, and the software reports a connection failure. If the scanner USB connection is un- and replugged, the slit returns to it's home position and it works again.. for one scan. Some time ago, the scanner worked fine. I don't know how long this is ago.
