Windows 7 – Playstation 2 Controller to USB Adapter Issues

With Device Remover I was able to get rid of the fake driver completely, afterwards I installed the correct driver.

You are correct about what directInput is vs Xinput, though one could argue that the directInput api allows for more diverse controls. If you have a controller that registers as a directInput device and you have a game that only accepts Xinput, I suggest x360ce (@ http://www.x360ce.com/ ). This converts directInput into Xinput for the game while masking the controllers actual input. Simply run x360ce.exe inside the game directory and follow the x360ce website's instructions. Unfortunately it is not compatible with all games, and also may not be compatible with your controller. It's worth a shot though, just be sure to leave feedback for the developers of x360ce afterward. I hope this helps!
