|
* Force feedback support for Mayflash game controller adapters.
|
|
*
|
|
* These devices are manufactured by Mayflash but identify themselves
|
|
* using the vendor ID of DragonRise Inc.
|
|
*
|
|
* Tested with:
|
|
* 0079:1801 "DragonRise Inc. Mayflash PS3 Game Controller Adapter"
|
|
* 0079:1803 "DragonRise Inc. Mayflash Wireless Sensor DolphinBar"
|
|
* 0079:1843 "DragonRise Inc. Mayflash GameCube Game Controller Adapter"
|
|
* 0079:1844 "DragonRise Inc. Mayflash GameCube Game Controller Adapter (v04)"
|
|
*
|
|
* The following adapters probably work too, but need to be tested:
|
|
* 0079:1800 "DragonRise Inc. Mayflash WIIU Game Controller Adapter"
