Magic mouse USB cable
I would recommend using a wireless USB mouse (uses 500 Hz or so) and comes with a little mini USB that you can use to plug-in to the PC. Logitech has a couple like this, you may have to look around for some.

But if you are looking for one for a Magic Mouse, you won't find one.

If you are concerned about accessing all of the Magic Mouse features with a wired/wireless (USB) mouse then I recommend finding one that uses gestures or has multiple buttons (like a gaming mouse).
