I have a new Creality 3D PAD that I am trying to use with a Ender 3 Max running Marlin 2.0.8. I can connect to the printer using Octoprint through the USB port and all works fine.

Connecting the 3D Pad to the USB port doesn't communicate. In the upper left corner of the 3D Pad it shows the word Commun.... in green. The display works as it should, but doesn't activate anything on the printer. Would a firmware update help?
