I bought a Nikon Coolscan LS30 two weeks-ago.
Since then I've been working on making it run under SANE.
I somewhat succeded to start the NikonScan - software provided with
the scanner under Wine and the TWAIN interface comes up.
I can do Prescans, but Preview or Scan fails.
It looks like it breaks when it is trying to do the autofocus...
Next, I dummed all the commands that pass through the
Wine aspi interface (-debug-msg +aspi) and since
then I am trying to figure out which command corresponds
to what in the Sane-backend for the Coolscan LS20 written
by Didier Carlier.
Even without beeing able to get it work completely:
Hats off the Wine-team for the good debug-features
integrated into Wine. When Wine will be more stable
on these (difficult) hardware issues it will be the ideal
tool for Scanner protokol analysis.
It is a fun project, but it is also not very easy, as quite
some protokol changes have been made and without the docs
its like playing detective.
Right now my modified Coolscan backend can do about as much
as the Twain interface under Wine: Detect the Scanner,
get some parameter information from it and do a prescan.
If anyone has had any more success about getting the LS30
to work under Wine I would like to hear about it, so
that I can analyse what is going on on the ASPI interface
during scan.
Has anyone experience about listening to a SCSI-bus under
Windows? Is there a tool to dump all SCSI transfers?
This might help to figure out what is going on.
