I have installed plustek-sane-0_39_7 with sane-backends-1.0.5. I needed to
hack the code to get it to compile: the file plustek.h refers to
definitions from plustek-usb.h which do not get included if you do not have
a USB scanner.

Once I had the driver installed, I scanned a few photos and they look fine
to my untrained eye.  However, I cannot scan larger objects. When I set the
-y vales to greater than 150mm I get the ominous 'Error during device I/O'
message.  Setting the debugging variable and recompliing the driver, I
invariably see the following:

  ReadOneImageLine() failed at line 299!
 
It seems to that the capabilities of my scanner[1] are not correctly
set. Some constant is set to 300 and should be a bit larger. Anyone have
any suggestions?
