I've worked on drivers for those two chips in the past. I have a large
amount of experience with these parts.

Correct, no Linux drivers.

Correct. Linux has no support for that device. :(

That's odd. It suggests an (off topic) windows related driver problem,
or a virtual machine issue.

I don't think the virtual machines work that way, at least not in my
experience. I've always been able to do what you want to do on various
platforms. Sorry, I can't really help you debug Windows / Virtual
machine issues.

Unlikely. Sigma are generally GPL unfriendly.

I've done drivers for this chip on OSX before, mostly as a R&D
exercise, so I'm highly familiar with it. The chip is a monster to
write for, kinda nasty to be honest - not very straightforward.

I think you're out of luck.
