One Midi keyboard (E-Keys49 from Evolution) sends VID 0A4D, PID 0099 and receives all keystroke date via USB correctly.
Second Midi keyboard (Oxygen49 from M-Audio) sends VID 0763, PID 3102. But no keystrokes or other Midi data are received.
I use Mini USB Shield 2.0 with MAX 3421E on ESP32 controller.
Any idea or workaround?
