Hi, I'm Elise, and I'd be happy to help with your issue.
Unfortunately it’s a reasonably old device now and I believe it is no longer officially supported, which is why there will be no drivers available.
As far as I can see Emuwheel is probably the best way to get this working, what I would suggest doing is running a virus scan on the download if you are concerned. But it seems to have support among the Forza gaming community.
Kind Regards,
Elise
