/*

 * Force feedback support for ACRUX game controllers

 *

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

 * by several vendors. They often share the same design as the original

 * Xbox 360 controller.

 *

 * 1a34:0802 "ACRUX USB GAMEPAD 8116"

 *  - tested with a EXEQ EQ-PCU-02090 game controller.
