You need SANE 1.0.6 for this scanner.

If you don't use devfs, and your distribution didn't take care of
this, you must create this file on your own. There is some docu about
that in /usr/src/linux/Documentation/usb/scanner.txt. Try something

mknod /dev/usbscanner0 c 180 48

After this, sane-find-scanner should be able to detect your scanner.

Can you see the scanner at /proc/bus/usb/devices ?
