problem with COD4 with a wired and wireless controller...

ok, i have a wired (in my case, it's the GH2 X-plorer wired guitar) and wireless controller, and when both are connected and i go the Multiplayer screen and then go back to the Single Player screen, the wireless one stops working with the game but still looks like it's connected because the green light is on. the guide button works, and everything on the wired controller works, but all of the joysticks and all of the buttons other than the guide button on the wireless controller stop working...

if i hit the guide button on the wireless controller, and log out then log back in, the wireless controller works fine again...

i tried it with a few of my other xbl titles, and this doesn't seem to happen on any other games, so i take it this is only a COD4 problem? i went to the COD4 homepage, but there's no link to send them an e-mail about it...

yeah, then the controller will work fine, but it's a bit annoying because i play GH2 and GH3 more than anything else. too bad the wireless guitars weren't better quality, you would think that they would get better with time, not worse...
