sane_init/read_dlld: attempting to open directory `./dll.d' sane_init: SANE dll backend version 1.0.13 from sane-backends 1.0.23 I tried scanimage -L in debug mode (omitted lines are marked with ): I tried to remove the xhci_hcd module (USB 3.0) and load ehci_hcd instead (USB 2.0), but this disables all my USB ports (dmesg shows nothing when USB devices are plugged in).
(based on Ubuntu 12.04, Kernel 3.7.0-7-generic) on an old Asus Eee PC 4G (no USB 3.0).
