As has been widely reported, with update 4.0 of the Switch OS, Gamecube controllers can now be used to play games on the Switch when connected to the Switch dock with a Nintendo first-party Wii U Gamecube adapter.

However, when I connect my Gamecube controller to my Switch dock via a Wii U adapter (all genuine Nintendo parts), the controller is not recognized by the Switch -- the only controller it shows as being connected are the pair of Joy-Cons.

My Switch is in its dock and it is (successfully) connected to a TV.

I have the Wii U Gamecube controller adapter connected to the Switch dock by plugging both USB-A cables from the adapter into the two USB-A ports on the outside of the Switch dock.

Things I've tried:

  • Verifying that my Switch does have the version 4.0 OS update.
  • Manually having the Switch detect new controllers by going to the "Change Grip/Order" screen and then pressing and/or holding the L and R buttons on the connected Gamecube controller. (Nothing happens.)
  • Test the Wii U adapter and Gamecube controller with Smash Bros. for Wii U to verify they still work ok.
  • Reboot the Switch. (Actually rebooting, not just putting it to sleep and waking it.)
  • Unplug and replug the USB cables from the adapter into the Switch.
  • Swap the order of the two USB cables from the adapter.
  • Try different ports on the 4-port Wii U Gamecube adapter.
  • Try using a different Gamecube controller.

Why isn't this working? How can I make my Switch recognize my Gamecube controller connected via a Wii U Gamecube controller adapter?


The only things from your process that I see might be an issue are that:

  • only the black USB-A cable needs to be connected from the adapter to the Switch dock
  • and you have to hit both the L and R triggers on the Gamecube controller to link to to the Switch after you connect the adapter with the controllers attached.
  • I gave it another few tries, both with only the black USB cable connected, and both the black and gray cables connected. I'm definitely copiously hitting L and R, individually, together, and holding them down. No luck yet, but thanks anyway! Oct 27 '17 at 12:30
