download a registry editor such as PHM registry editor and go to \default\default and add a new key called "1_5"
Then under the 1_5, add another key called "Gamepad" then under that add a new string value called "DLL" and the value date called "HIDGAMEP.DLL" then hit ok then ok again.
Do a soft reset and everything should be working. You will know if the gamepad doesnt work if you dont get a popup saying your gamepad is connected. Not all gamepads will work with this early driver so you have to try many to find one or find one of the 2 i mentioned earlier. Even if you find one that works, make sure all directions of the thumb pad work and all the buttons (or most)
