[sane-devel] canon DR series in SANE

[m. allan noah]

tony et al:

i have had some relatively high-level contacts with canon corporate a
few months back about getting the docs required to write a driver for
the DR series scanners. I think their management is a little confused
about the idea of anyone doing such work for free. i have a feeling
that the basics of the scanner protocol could be reverse engineered
from windows USB traces, but it would be much easier with docs.

if you want, you could try contacting some of their folks and asking
for linux support. contact me directly, and i will give you an ear to
bend :)

This is generally driven by "ISIS" (Pixtran / Captiva ) drivers in Windows and is a high-speed document imaging scanner.  http://www.captivasoftware.com/products/pixtran.asp  Captiva was at first hopeful they could help with a Linux solution but finally stopped returning my calls.
