I switched both connectors and that was it.When both USB cables are connected it's either a bad USB port on the Wii U, a bad adapter or a bad controller.
For me, with MayFlash Adapter, and original and non original controllers, the rumble would work, just activate the settings on Nintendont and the gameAny update on this? I am considering buying an adapter and two GameCube controllers to play VC injects, but if rumble doesn't work it makes me hesitant to spend the money.
Thanks for your response! I got the official one, and two controllers. It works great! Rumble in the GameCube controller is surprisingly good. It has been a while, so I forgot.For me, with MayFlash Adapter, and original and non original controllers, the rumble would work, just activate the settings on Nintendont and the game
