Yes, but you need a $80 adapter to do it. I have to find out for you what it's called. I know on the DDRFreak forums people use those to use there dancepads on the 360

Edit: It's called the XFPS 360 and XFPS 360 Pro

Edit:: There's a XFPS 360 on ebay right now for 75 shipped and a XFPS 360 Pro for 90 shipped
