Well I think the right solution would be to add support for your scanner
to SANE. Then Wine should be able to use it using the twain dll (see
dlls/twain) which acts as a bridge to SANE.
Interfacing directly with the scanner might work using Wine's brand new
and very incomplete USB interface (I believe part of it is in setupapi)
but that would probably be more code and you would still end up writing
what is essentially a driver. In other words in either case you will
probably need the hardware specifications.
