I'm not saying this is necessarily a bug in the Microtek backend, but
just because it works with scanimage doesn't prove that it's a bug in
the net backend or in saned either. Maybe you can try to use
SANE_DEBUG_NET=128 on the client side and/or "saned -d 128" on the
server side to try to track the problem down?
Heh, I've never actually tried 'saned' myself. I'll give it a shot over
the weekend, and see if I can find/fix any bugs.
As far as resetting things after a hang: I've noticed that typically, when
I do something that hangs the scanner, often the scanner has barfed on some
command and reset itself, leaving another scsi command hanging off the bus.
If I wait some unreasonably long time (~5-10 minutes), the aha152x driver
will time-out and scrap the hanging command, and then I'm free to go and
do it again. Maybe the driver for your 2940 will do the same.
