Yes.

Right, but that would be easier, if the list would set a Reply-To
header that points to itself. Is it possible for the list maintainer
(is that you, Gerhard?) to configure the list that way, or does
linuxhacker.org not support Reply-To headers?

That was my thought, too.

I'll have a look into the other SANE backend which has rudimentary
support for the Epson 1250 (HP scanjet 2200)....

Sorry, that's my fault. I mixed the high and low halfbyte of Register
5B. So the lamp is controlled by misc I/O 6 which can be set by the
higher half of 5B.

I'm in the development departmend, and my main job is maintaining
packages (e.g. Tcl/Tk and PostgreSQL).
My participation here is more of private nature, although I also spent
some working hours on investigation.
