Maybe hotplug problems:
check sane-backend/tools/hotplug  (README) and files
check etc/hotplug/blacklist on disabled kernel modules
check /etc/fstab          none /proc/bus/usb  usbfs  defaults 0 0
and  maybe                none /sys/bus/usb   usbfs  defaults 0 0

check with /proc/bus/usb/xx/yy on rw rights for scanner
