It recognised my scanner :-), but failed on reporting dimensions / 
resolutions ...

I did not try to scan, but made some changes to the code in attach, which I 
am attaching (of course!), as well as a log. The relevant parts have comments 
with questions.

I have two questions (and a side note) which may be of general interest to 
the list:

a) coolscan uses sane.type = "slide scanner",
   canon uses "film scanner".

   Shouldn't the same name be used for both?

b) Is there a backend that implements film strip sense/control (and works)?

c) From backend/coolscan.c "This file implements a SANE backend for COOLSCAN 
flatbed scanners." Flatbed coolscan?
