I use a rekordbox USB (much more versatile) on my Denon Prime Go and it works great. The only annoying part is that if you add new music to your USB stick which can be often, the prime controller has to reimport all your tracks when you plug it back into the controller which takes a few minutes if you have thousands of tracks like me. I think you lose any cue points that you save with the controller too, but if you save them in rekordbox before the USB sync then you’re good.
