4  * a «generic» hid gamepad called "Thrustmaster FFB Wheel".
6  * When in this mode not every functionality of the wheel, like the force feedback,
7  * are available. To enable all functionalities of a Thrustmaster wheel we have to send
8  * to it a specific USB CONTROL request with a code different for each wheel.
10  * This driver tries to understand which model of Thrustmaster wheel the generic
11  * "Thrustmaster FFB Wheel" really is and then sends the appropriate control code.
