Yes, I saw you were the author of the backend, so I was hoping you'd
be chiming in to reply :).

I still have this particular scanner here and there is even a driver
supplied by Canon in source which includes a binary blob, however,
so I'm not sure whether you can find the proper control sequence in
the sources. I have already skimmed through the source code and found
nothing so far.

Do you have any idea what we could do to find the proper command to
set the scanner into scanner mode? Would a USB dump on Windows help?
