2 | * Force feedback support for various HID compliant devices by ThrustMaster: | |
3 | * ThrustMaster FireStorm Dual Power 2 | |
4 | * and possibly others whose device ids haven't been added. | |

6 | * Modified to support ThrustMaster devices by Zinx Verituse | |
7 | * on 2003-01-25 from the Logitech force feedback driver, | |
8 | * which is by Johann Deneux. | |
