3 | * Force feedback support for Mayflash game controller adapters. | |
4 | * | |
5 | * These devices are manufactured by Mayflash but identify themselves | |
6 | * using the vendor ID of DragonRise Inc. | |
7 | * | |
8 | * Tested with: | |
9 | * 0079:1801 "DragonRise Inc. Mayflash PS3 Game Controller Adapter" | |
fe6cc17f MH |
10 | * 0079:1803 "DragonRise Inc. Mayflash Wireless Sensor DolphinBar" |
11 | * 0079:1843 "DragonRise Inc. Mayflash GameCube Game Controller Adapter" | |
12 | * 0079:1844 "DragonRise Inc. Mayflash GameCube Game Controller Adapter (v04)" | |
f8690450 MH |
13 | * |
14 | * The following adapters probably work too, but need to be tested: | |
15 | * 0079:1800 "DragonRise Inc. Mayflash WIIU Game Controller Adapter" | |
