I meant to write -L, not ->, up there but I think you figured that

Did you also update the firmware line near the top of snapscan.conf.
Note that it can only handle *one* such line.  If you dumped your
esfw3e.bin in /usr/local/share, you should have

  firmware /usr/local/share/esfw3e.bin

in there.

No, don't.  If you don't want SANE to try all the backends installed,
comment out the ones you don't want in dll.conf.  So if you only want
to try the snapscan backend, comment out all the others.

You should be using "usb 0x04b8 0x0120".  That is assuming the USB
product ID is 0x0120 (I don't remember off the top of my head).
