Problems:

The reset command (int) crashes the scanner in some cases.

There is no check for correct arguments for definition of the scan area.

The coolscan LS10 SCSI interface has a very buggy timing. So the
command for scanning doesn't work correctly. I'm now using the
command for scanning single lines, which works correctly, but it
is a little slower. 

The prescan command doesn't work correctly for dark images. 
But it also doesn't work correctly with the Windows
Software from Nikon.
