2 * Force feedback support for Mayflash game controller adapters.
4 * These devices are manufactured by Mayflash but identify themselves
5 * using the vendor ID of DragonRise Inc.
8 * 0079:1801 "DragonRise Inc. Mayflash PS3 Game Controller Adapter"
9 * 0079:1803 "DragonRise Inc. Mayflash Wireless Sensor DolphinBar"

11 * 0079:1844 "DragonRise Inc. Mayflash GameCube Game Controller Adapter (v04)"
13 * The following adapters probably work too, but need to be tested:
