Have you tried to run it in Compatibility Mode with Vista SP1? In fact, why don’t you simply download the Vista drivers and install them under Vista SP1 compatibility?

It’s worth a try. I have forced many of my Vista drivers to install successfully on an unwilling Windows 7 by running them in Compatibility Mode.

How do you run it under the compatibility mode?

Thanks!
