  And I still do not know why some of the X6's work with the TMA option,
  whereas others don't. This is especially true for grayscale mode, because
  in grayscale mode the backend simply copies the data as they are transferred
  from the device into the application buffer.

  As I wrote in my other mail older versions of the backend had a problem
  with pixelized images on an X6. The solution was to exchange two of
  the SCSI commands. Maybe something similar is necessary in this case.

  If possible, can you trace a scan (with wine, for example) and compare
  the output with the debug output of the backend or send me the output ?
  I do not have a TMA and cannot test it. When I force the backend into
  TMA mode it silently starts scanning from the flatbed, but the colors
  and size of the image are OK.

  Bernd
