Windows Device Manager shows error: "This device cannot start. (Code 10)"

[ccarmatic]

I am using Windows 11 and an Arduino Zero

this is my code, the version of MIDIUSB is 1.0.5

#include <Arduino.h>
#include "MIDIUSB.h"

unsigned long prevtime = 0;
unsigned long time = 0;
int prevvalue = 0;

void controlChange(byte channel, byte control, byte value)
{
  midiEventPacket_t event = {0x0B, 0xB0 | channel, control, value};
  MidiUSB.sendMIDI(event);
  // MidiUSB.flush();
}

void setup()
{
  prevvalue = analogRead(A0) / 8;
}

void loop()
{
  digitalWrite(LED_BUILTIN, LOW);
  time = millis() - prevtime;
  if (time > 50)
  {
    digitalWrite(LED_BUILTIN, HIGH);
    uint8_t value = analogRead(A0) / 8;
    if (abs(value - prevvalue) > 5)
    {
      prevvalue = value;
      controlChange(1, 1, value);
      MidiUSB.flush();
    }

    prevtime = millis();
  }
}

I flash the code to the Zero using its debug USB port and I can verify that it is working because the builtin LED flashes correctly and the transmit LED lights up when I turn the trimpot connected to A0

But when I connect the Zero with the native port (which MIDIUSB uses), I see this in Windows Device Manager:

This device cannot start. (Code 10)

A device which does not exist was specified.

an entry with the Arduino Zero name at COM7 which 'does not exist' to Windows, and a 'USB Serial Device' at COM6

The Arduino Zero is not being detected as a MIDI device , but Arduino IDE can access COM6 to upload sketches and open the serial monitor on the native USB port

If I upload any other sketch , which does not contain MIDIUSB, everything is normal in Windows, in Arduino IDE, and on the Arduino Zero. This leads me to believe that the fault lies in MIDIUSB

    if you are on Windows, it may happen that the drivers for the new composite device are not getting loaded correctly. Try uninstalling all the drivers currently loaded with the board (from Device Manager) and if you are on windows 10 it should reinstall the correct ones. For further explanation, please read this thread that almost completely applies (https://github.com/webusb/arduino/issues/44)

Hello, I have tried the uninstall and reinstall drivers method without success - until I closed the Arduino IDE and did it again - the IDE was preventing Windows from deleting the necessary drivers
