That is correct. The mustek-scsi patch is for the Mustek SCSI adapter

Ok, in this case, try rebuilding SANE with configuration option
"--disable-ld-fix". Something like:
should do the trick (the "make distclean" _is_ important). Can you try
this and let me know how it works?

I see two possibilities:
(a) The height of the scanner is not correct. At present, mustek.c defines
the height to be 360mm for your scanner type. If that's not correct,
could you measure the width and height of the scan area and let me know?
(you could also experiment/change with the width and height as defined
around line 339 in backend/mustek.c).
(b) The SCSI driver times out while acquiring the preview. If this is the
case, you'll have to hack the driver. You should see messages in
/var/log/messages if this happens.
Hope this helps,
