Okay, so I got the Tekken 6 bundle with the wireless stick for the Xbox 360. Next, I bought a wireless 360 receiver for my PC, and yes it is stamped with the Microsoft Seal of Approval, and plugged it in. But when I tried to connect my wireless fight stick to it, nothing happened. I followed every single piece of advice I could think of, including turning off ANYTHING wireless in surrounding area. I even turned off my cellphone and unplugged my mouse and router/modem. And, no the stick is not broken. It even turned on my 360 in the other room when I was trying to connect, so I had to pull the plug on it (the 360). After determining that it probably wasn't wireless interference, I decided to test if the adapter even worked. I got my regular controller, turned it on, hit the connection buttons on both devices and, voila, it worked. It still doesn't want to connect to my fight stick, even though everything else works.
Any ideas? Or should I get a different one to see if that helps? Or attempt to mod one/make one from spare 360 parts? Not that I have anything I can mod it with.
