Strange, I've been having the same problem on one of my computers, but multiple 360 controllers work just fine on the other one.

Both machines have Windows 7 x64. When I have the problem, gamepadconfig.exe notices that there are 2 controllers. Configuring the first controller works fine, but no button presses are recognized from the second controller.

I also tried transferring gamepads.txt from the working machine to the failing one, with no luck. This means that both wiispace.exe and gamepadconfig.exe have the same problem.

Let me know if there's any more information I can provide. Because I have 2 similar machines with different behavior, it may help with the debugging.
