Hi Jackson,
When using Rekordbox with ProLink make sure the USB cable used for performance mode is NOT connected. It should work directly from your PC/Laptop but using a lanhub/switch is also fine.
I've got mine setup with a switch in between. Just make sure your USB cable is disconnected and your RB is in Export mode. A "LINK" button should pop up at the lower left corner in RB. Press rekordbox on your XZ and you're good to go!
Hope this helps you out
