Dolphin doesn't recognize Xbox controller

[CNW]

I have a wired Xbox controller that I used with Dolphin, and it worked fine.  However, after redownloading Dolphin, it does not allow me to use the controller under Controller Configuration as a device. The controller works on the computer still. How can I get Dolphin to recognize the controller?

Does the drop down list not show it?

Yeah, only the keyboard and mouse show up.

I was able to fix it by restoring my computer to before I had the xbox controller downloaded, then I redownloaded it. It seems like this isn't a dolphin problem, just an xbox controller problem.
