[sane-devel] Scanner - Penpower card scanner

[tony mollica]

Hello.

I have a business card scanner from Penpower that scans cards up to 4x6 
inches that I would like to have work with xsane, or any other scanning 
program that can be used with Linux.  I looking for a best way to attack 
the problem to make this work. sane-find-scanner can locate the hardware 
but xsane won't recognize the scanner.  I need to know where to start 
solve the problem. I've attached info from several sources below. Shows 
up as a Plustek with possibly a GT-6816 chip. Thanks in advance.  Any 
suggestions?
