please check if your usb interface stays on status power/control=on. If 
it is on power/control=auto (usb autosuspend) some usb-scanners have 
problems.
On ubuntu 12.04 there seems to be a problem with udev rules: make a test 
moving /lib/udev/rules.d/40-libsane.rules to ../99-libsane.rules. Don't 
forget udevadm control --reload-rules and replug the scanner.
