Hello and Welcome to the forum..
Well if you've already tried the latest available Windows Vista drivers and have already tried running it in XP through Compatibility Mode than it's looking like your just going to have to wait until some Windows 7 specific drivers are released for it..
Unfortunately..
I guess you could try running it through the new XP MODE within Windows 7...
That may work as well.
If you need help with that just let me know....
