XBMC4Xbox

Hi,
Since a few time I'm experiencing problem with the wireless controller for Xbox.
The problem is: thumbsticks and dpad works from time to time and often not at all.
Often It looked like the right thumbstick worked bad, decreasing the volume to mute
rapidly when xbmc started up. With thumbsticks disabled (via keymap.xml) the dpad still doesn't works.
The pad has no problem, I tested it with evolutionx dashboard and playing Doom3.
I had no problems with the wired controller.
I installed the latest stabile build (3.2) hoping was a known issue but it didn't help.
