Hi Yuuichi,

I hope you can help or fix my problem.

I have a MEDELI AKX10 Keyboard. The Keyboard provides USB MIDI and USB AUDIO over the USB Port.

But, the USB-HOST Shield isn't recognized by the Keyboard !

Is there some tweaking nescessary and possible to work with the MEDELI Keyboard

Many thanks in advance for your reply Dennis

Please enable debug mode and run USBH_MIDI_dump.

I don't know exactly what happened, but after enabling the debug mode and executing the Midi Dump Sketch the Arduino and the USB Host Shield are now recognized by the keyboard and MIDI is both sent and received.

Thank you and best regards Dennis
