Does anybody have experience with a Mustek ScanExpress on a non-Linux
system? On my Linux box the ScanExpress 12000SP is connected via
the DTCT436 card shipped with scanner. The scanner is detected and
reacts (to some extent) to the SCSI commands.
After twiddling around with the backend (sane-0.70) I am now convinced
that the command set (Thanks, David!) of the scanner itself is not the
real problem.
There seems to be a flaw in the SCSI driver on either side because
after mode_select a get_image_status just echoes the parameters of
the previous mode_select. I tried several weird numbers as parameters
for mode_select, always the same effect. Without a request_sense
between the commands it becomes even worse. Probably a timing or
handshake problem. Used kernel 2.0.32 and mustek patch.
