@ogteeg If your controller is detected, then you're not experiencing the same issue as in this topic.
My advice is to make sure you're fully upgraded (OS/Packages and RetroPie), install the xpadneo driver from RetroPie-Setup (see here on how to install packages in RetroPie) driver section and then re-try the pairing. Make sure you remove the controller from the list of registered devices before attempting to re-pair.
If that doesn't work, then open a separate topic and provide more info about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.
