/*

 * Force feedback support for DragonRise Inc. game controllers

 * From what I have gathered, these devices are mass produced in China and are

 * distributed under several vendors. They often share the same design as

 * the original PlayStation DualShock controller.

 *

 * 0079:0006 "DragonRise Inc.   Generic   USB  Joystick  "

 *  - tested with a Tesun USB-703 game controller.
