[sane-devel] Backend for plustek Opticbook 3600

[Chris Berry]

Hey Stef, I had to take a little time off the front end stuff to do some 
documentation but Im looking at it again now. Like you im fairly certain 
everything else is set, could you share with me a snoop of the HP3670? 
I'm curious to see the front end entries and whether they follow a 
similar pattern to the opticbook 3600.

Cheers

Chris
