Success with renaming ATMega32U4

[MiqViq]

Hi all,

Finally I found a working way to set the device information on Arduino Pro Micro.
This method probably works on other boards too which are based on ATMega32U4.

Here is the link to the source files:
https://github.com/mon/Arduino-USB-Rename

You will need to include these 2 files in your sketch:
usb_rename.cpp
usb_rename.h

This example sketch programs Pro Micro as a basic MIDI USB <> MIDI Serial converter:

/*
 * Simple USBMIDI converter v0.1
 *
 * Forwards MIDI messages from USB to MIDI and back
 * If you short TX and RX pins of arduino, it should act as MIDI loopback
 *
 * Note that Serial1 is used by Arduino Leonardo
 * Serial port on your board might have different name (eg.: Serial, Serial2, ...)
 *

#include "usb_rename.h"
#include <usbmidi.h>

// Product name, Manufacturer, Device Serial Number
// Any argument can be left off, or NULL to keep the original Arduino name
USBRename dummy = USBRename("PedalinoMini-EFC40A24", "MY_COMPANY_NAME", "EFC40A24-2022-1009-210520");

void setup() {
  USBSetup();
  Serial1.begin(31250); //MIDI baudrate
}

void loop() {
  //Handle USB communication
  USBMIDI.poll();

  //Forward MIDI
  while(USBMIDI.available()) Serial1.write(USBMIDI.read());
  Serial1.flush();
  while(Serial1.available()) USBMIDI.write(Serial1.read());
  USBMIDI.flush();
}
