Input configuration for the Logitech G29 Driving Force GT Racing Wheel.

Put this into the ActionMap folder inside the game directory.
Then add a new line inside the actionMapPaths.xml referencing this file.

Grid doesn't seem to recognize the wheel when plugged into an USB 3 slot; at least on my system.
