@hank it worked thank you

Try installing the hid-nintendo kernel module, should have better support for Nintendo related gamepads than the default kernel module included in RetroPie.

This has been updated, and now includes Flick Stick control mode:

You must select it in the "options" menu -> "gamepad" -> "sticks config" -> "layout" option.
Southpaw variant available, just like the rest of the layouts.
Just wanted to post, because it's probably the first game with this control method available in a Pi. Works with no issues in a RPi3B+.

@ZackPlonk said in Trouble re-connecting Nintendo Pro controller:

I'll set that up and report back on how it works out...

@eberhab 's script works like a charm and my pro-controllers are now happily reconnecting to the RetroPie system after they have been used with the Switch

Thanks for your help!

Thanks Clyde, I'll keep that solution in mind. I know knockoff PS3 controllers are tricky. Thanks for your help :)

FWIW I read on another forum about someone havin the exact same issue with Wii U Pro controllers. They ended up buying a dongle and it resolved the problem.

So, any clue why those things are happening?
The 8bitDo not being correctly usable, and the Switch pro regularly losing connection.
