  Advanced RawHID example

  Shows how to send bytes via RawHID.
  Press a button to send some example values.

  Every received data is mirrored to the host via Serial.

What is your problem? This does not seem related to hoodloader2.

Nico, great thank for your job ! Its very usefully. I can't make combination RAW HID + Serial1 for link Uno with PC by HID instead Serial. If remove Serial1 from sketch and replace by UART then work..

I am not sure, I think rawhid does not work in general. I am not sure why it even works with your solution
