HAL USB MIDI Host code, MIDI stays in "Idle" mode, no data received.

Everything in the code seems to be working properly in Debug Mode. As soon as a keyboard is plugged into the USB-OTG port on the board,  the USB-Debug log shows the MIDI class is started, the Init routines run, the endpoints are linked to MIDI In and MIDI Out, and MIDI Process seems to be armed and ready to accept MIDI input from the keyboard.

However, when I play a note on the keyboard, I notice no data is being received. The MIDI core is idling, as if nothing is being output from the keyboard.

Does anyone have any thoughts about what could be causing this? 

Thank you!!

Christopher
