[sane-devel] need help with Microtek 35t+ on SPARC/Solaris

> Hi, I am having problems making SANE work with a ScanMaker 35t Plus.

I have 35t+ with linux and sane 1.0.7 didn't work either (I have not
tried with 1.08).

However, as coded it couldn't load 10 bit gamma tables. I don't know
what is wrong, but I got it "working" by forcing 8 bit gamma tables by
modifying the "microtek.c" with the attached diff.

HOWEVER! It definitely not correct, I think it results somewhat odd
gamma table, but at least it scans!

Several months ago I asked on this list who maintains the microtek
backend, and nobody appears to do so.

I could FIX things, if I had the 35t+ programming info. Has anyone
actually managed to get those from Microtek?

I'm fairly pissed off by these scanner makers hiding the info. Is
there *ANY* scanner maker that gives programming info? If so, my next
scanner will definitely be of that brand!!!! (I won't buy anything
from microtek any more).
