Is the scanner listed in /proc/bus/usb/devices? If not, something with
your kernel USB system is wrong (wrong driver?).

If yes, does sane-find-scanner find the scanner? If it's not found
even as root, you may not have libusb-0.1.6 or newer. When you build
sane, configure prints a line like this "Libs=-lusb ...". If the -lusb
part is not there, libusb was not found. YOu may need to update your
libusb in this case.
