You are welcome, glad to help on using open source solutions.

Well, as I mentioned earlier, I've made native (non-Cygwin) versions
of the libraries, although didn't commit them. Not sure when I could
have a time to update the patches for the current SANE backends. As a
starting point, I could sent you compiled binaries along with the
patches (they are against sane backends 1.0.18)

I've ported Xsane to Win32 too, although it's a bit old (XSane 0.991).
In general words, I was interested in a complete frontend solution for
Win32 and ported all necessary parts (SANE libraries, scanimage and
XSane). The XSane patches weren't sent to mainline as well. I could
give you the all libraries and binaries, along with patches, so you
could try to use them and reduce implementation time, if the solution
suits your needs.

Haven't even heard about such device. Usual way to check whether a
device is supported is:
- take a look at list of the devices supported by SANE
(http://www.sane-project.org/sane-supported-devices.html)
- take current GIT snapshot and compile it
- gather all device information (vendor, 'sane-find-scanner -v -v -v' output)
- try to scan
- report your findings on the sane-devel mailing list

Perhaps, someone could recognize the device and give you some suggestions.
