Controller connected via BT and USB and Terminal says 'adding epoll_subscriber: fd=4'

That's all, but question: how is the mapping? I want to use it not only for gaming. (Designing PCBs in KiCAD, Pixel the files for the GUI of my Project and Minecraft!)
By the way, here is the OS I'm using: Zorin OS 17.2 Core
And the Controller is a PowerA Nano Pro Controller, BT recognizes it as "Lic Pro Controller"
