Some had no problems others had your problem, me included! I got mighty peeved with CoD not recognising my X52...you are not alone! Make sure your stick is ok in the Windows control properties box. You then need to set it up in the controls menu of Cod as an input device and asign axis and switches manually.

In the controls Axis menu there are two options on the lower left of the screen - 'change' and 'clear'. In the end, I kept the mouse on one of them with mouse button pressed and I waggled the joystick frantically. You will know if its worked as the sensitivity sliders suddenly spring into life and respond to your joystick inputs.

Once Cod recognises one of the joystick axis the rest just seem to work as normal. Best of luck and see what others say!
