There's been mention of an xbcd driver and one or two others. Don't have an Xbox 360, or an Xbox 360 controller, so I don't know anything about it. Sensitivity should just be the default (1.0). It's just the only thing that made sense that I could think of that could cause that problem.

Note: Just because I can't think of anything else that makes sense doesn't mean there isn't anything else. Or that the cause of the problem necessarily makes sense.
