2 | * Force feedback support for DragonRise Inc. game controllers | |
3 | * | |
4 | * From what I have gathered, these devices are mass produced in China and are | |
5 | * distributed under several vendors. They often share the same design as | |
6 | * the original PlayStation DualShock controller. | |
7 | * | |
8 | * 0079:0006 "DragonRise Inc. Generic USB Joystick " | |
9 | * - tested with a Tesun USB-703 game controller. | |
