I have kernel panic with this driver unfortunately. Wired XBox 360 with iMac 2011 and MacBook Pro 2012. Not sure what caused the issue... Because of it, I installed Windows via BootCamp and play all games over there, a bit inconvenient.
Which version of Xbox360Controller and what Mac OS version? You might want to try an older pre-64bit version of the driver if that will work on your OS.
Or you could try to debug the source if you're up for that. I would try but don't have the expertise to help without seeing it and tinkering with it.
