When your first at multiplayer menu you just press start on the pro controller and sign them in as guest. 

Thanks!!!

What a maze to get it to work.

It should let you, My brother and i played Blackops 2 that way, he used the gamepad i used the pro controller, What does it say when you try to sync them both?

Thanks for the response.  It doesn't say anything.  It just turns the opposite controller off. Only one is synced at a time.  We tried going into the menu to sync them both, but it only lets us account for the pro controller (or none).  That said, the Gamepad stays synced, but once we use it, the Wii U Pro unsyncs. 

Hey all, I'm having trouble playing Multiplayer (Black Ops 2) online.  Me and my friend want to play in a game together online.  He will use the Wii U Pro Controller and I will use the Gamepad.  For some reason, the system only lets us have one of the controllers synced at the time in Black Ops 2 (Gamepad or Pro Controller).

Can I use both at the same time?  Am I missing something?

Thanks!
