Err, 486DX2-66 - greetings from the past and a Intel Pentium (first release,
the one with the famous bug).... running RedHat linux 5.1 with sane 1.0.1...
my scanner is a medion flatbed scanner, the windows-vxd function
GetDeviceInfo says "Printer Scanner 1.00 Mustek MFS-600IIIP", the windows
file title of the vxd-driver is "A4SII300 EPP SCAN Device", asic-id is 0A5h,
ccdtype 0. More infos needed?
I have made same changes to your backend, Jeff. When compiled with -DNO_CALIB
the backend produces now pictures but the colors are all wrong. Something in
the initialization stage still must be wrong because the function calibrate()
(which seems to work properly) calculates a BlackRef of #204... not quite
possible...
the diff-file attached to this mail apllies to the package
musteka4s2debug.tar.gz
