I have no idea, but just thought id comment on the fact that in just buying a simple adaptor there could be a problem in mapping the buttons.

 

DC->USB by itself won't work. DC->USB->360 Keyboard/mouse thing. If the DC->USB adapter doesn't need drivers, then it might work, if it needs drivers, then it won't. Doubt it will work very well as it's expecting a mouse and keyboard and is set up for that (dead zone adjustment etc). The buttons along the top aren't for mapping anything, they are turbo buttons. You also need a wired xbox controller as well, as that thing has to use the authentication chip from it for it to work.

So probably better to get a proper 360 stick, as you're going to be looking at getting a DC-> USB, USB->360 Mouse & Keyboard thing and then on top of that, a wired 360 controller. So even if it did work, with that many adapters, one not even designed for it and a wired 360 pad thrown in, I'd expect some serious delay.
