This is done by the scanner itsself. It can't be influenced by the
backend directly. The extremely small buffer in the scanner gets full
and then it has to go back and start scanning again.

There is no difference in the SANE backend compared to the Windows
driver. The only difference seems to be that with some SCSI cards,
Linux seems to be a little bit slower or has a little bit more latency.
There are some tips that may or may not work on the mustek backend
