there is no workaround if your using wiiu pro controller on slot 2 on games that only use the slot one it wont work just unplug your gc controller and turn hid off, lots of games only read slot 1 unless they have multiplayer.
Workaround = "how do you get it to work?"
Plugging Gamecube in Port 2, AND unplugged booting it still does nothing.
The Wiimote is also lighting up like a Xmas tree.
Help?
