Only some people have this problem. It's unknown what causes it. There's another fix for it, which involves mashing buttons as you're connecting the controller, that works for some, while other need a WiiU to solve it.I was looking forward to buy the Wii U Pro Controller to use on my PC... but I don't have a Wii U
Do I really need to sync the controller with the console in order to work with this? Just once? or is this a recurring problem?
So only some people have the problem, and only some of those need a WiiU to solve it... It's up to you to decide whether you want to take the risk or not. You can always try and then return the controller if it doesn't work though...
