Well as notional maintainer/developer of the viceo
backend I had better get involved here.

The http://www.littlecms.com/iphoto/otlinux.htm has
the patches for the E4 based scanners, which included
a whole batch of code for the Windows drivers that
kwlee acquired from some unspecified source.

This is a generation newer than my scanner so I
contacted kwlee and got the source for the E3 scanners
to integrate. At this point I continued the
development which can be found at

I am more than happy to GPL my modifications, but none
of the scanner manufacturers will talk to me about
licencing the source code.

My scanner is from Genius, and their webpage points
back at my driver :->

I haven't heard back from Visoneer or Primax.

I'd love to get the code properly integrated. For now
it is a patch to various releases of Sane.

One other issue is the driver requires some
modifications to scanner.c/h which may now be
redundant. Can anyone help me out here.
