Can you a buy USB attachment for the 360 by itself? I was in the process of moving and I think I might have lost my USB connector cable that goes from xbox360 to the Guitar Hero guitar. I really don't feel like shelling out a bunch of money to buy a wired controller just for the USB attachment, but if I have to I guess I have to. I scanned through EBAY but I couldn't really find what I was looking for. Help?
