I am not talking about image size but about SCSI buffer size. With most
Mustek scanners and the Mustek SCSI adapters the scan stops after each read
command and backtracking occurs. So I am trying to scan with large buffers.
Standard is 1 MB at the moment. The scan speed is dependant from the
resolution and image with (but not from length).
