I use an Xbox controller
aswell. Here's what to do:
Press Start > Run then type in regedit.
Then click on the folder that has the name of your controller in the right hand screen. It'll probably be the bottom one.
Then right-click on OEMName and click Modify. Change it to Logitech Rumblepad
This makes your right analogue stick work, the only problem is that everytime you restart your computer you have to unplug your controller, rename the OEMName to the original one, re-insert your controller, and then change the OEMName to the Logitech one again.
