How can I find de controllers to Linux version...?

Hello averyone!!!

I deleted controllers folder trying to configured my Pioneer DDJ-SB3 on Linux.
I have 2 questions:
1- How can I find all the controllers to make it work Mixxx?
2- Where can I find the Pionner DDJ-SB3’s mapping?

Thank you so much!! I’m anxious to can play with my mixer!!

Support for the Pioneer DDJ-SB3 is supposed to land in 2.3.0:
