* 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 an EXEQ EQ-PCU-02090 game controller.
