I had a look at it too. Of course, I didn't get much out of it, because
I didn't know what I was looking for.

I looked at the inf file, and if I'm reading it right, there's no other
scanners supported by it. I'm not sure how much of the file I can
actually reference in this email without violating copyright, but I
think the only models of scanner mentioned in it are the HP4600.

I don't have access to the scanner, and my friend (who does) isn't quite
brave enough. If I get access to the hardware later, I'll certainly let
you know, but it seems unlikely yet.
On the subject of reverse-engineering the driver -- I understand that I
have no experience with this sort of thing at all, so feel free to say,
"No, that's hopelessly naive" -- but since there *is* a USB log, can't
we just pluck out bits and pieces of it and try to send them to the
scanner and see what happens, and reverse-engineer it that way? Some
brittle shell script or something that scans something sometimes would
certainly be a first step. (Of course, it would be hard to progress past
that with only one USB log, wouldn't it?)
Thanks again for your time.
