I bought an Xbox 360 controller a while back, thinking it was an original controller. It wasn’t.
My generic Xbox 360 controller didn’t work in Windows 7 by default, because the system didn’t recognize the controller. At first I thought that I needed the driver, so I headed over to Microsoft’s software download.
The driver software didn’t fix my issue. My Xbox 360 controller still didn’t work.
But, as it turns out, you can manually set the driver if you open Device Manager. That will force Windows to use the proper driver, and the controller will work.
The controller LED stopped blinking. Woo!
Works out of the box in Windows 8, though.
