we have lately been discussing the future versions of SANE. it might
happen that these older machines will not be directly supported, but
rather, require a compatability layer. I would not ask you to do
something you do not want, but consolidating those backends makes it
more likely that they will be kept alive in the future. now, you might
be the only living beneficiary :)

the backend devel and i are already working on that one :)

recent thread (january) on: Mustek ScanExpress A3 600 USB Pro comes to
mind. also an old machine i am afraid, but i was contacted by another
user of it today, so perhaps we can get you some debug logs, etc.
there has also been some discussion of rewriting the snapscan backend
to not access the device from both threads...

if you would rather look for a recent machine, it would seem that
there are quite a few Brother brand machines that are only supported
by a closed source backend. The same goes for some Canon and Epson
machines. A quick trip to your favorite electronics boutique will show
you many machines which dont work with SANE unfortunately.
