Interesting. I havn't tried to get it loaded by a frontend directly. I've
only tried indirectly via the dll meta-backend. Obviously I've missed
something somewhere...

It is via the dll backend. It spits out messages about opening and reading
the config file. It then opens the usb port and confirms the scanner is on
the other end. And then the frontend exitssaying it oculdn't find a scanner.

Hmm, I had to make up some numbers for those #defines. Nothing on my system
complained about them being wrong. Are they defined in sane-config.h?
Because I know I don't have that file.

Thanks for looking at it. I check again tonight.
