That is a factually incorrect statement. If you are willing to part with
money, then Vuescan supports this scanner under Linux.

There should at least be a recommended name for the option. It would

I have just taken a look at the SANE2 documentation, and a couple of
things have struck me about lack of support for some features in
filmscanners.
The first is multipass scanning. Basically what happens here is that
the scanner can read the values several times and returns the averaged
result. T

Why not rename the firmware files into a none clashing namespace,
then they can all go into a single directory. A suitable
