My ESP32-C3 keeps connecting and disconnecting on Windows

Context

I have an ESP32-C3 “SuperMini”.

Problem

When I plug it into my Windows 10 computer, it’s recognized but keeps disconnecting and reconnecting.

Solution

Once the ESP32-C3 is connected to the computer, just hold down the “BOOT” button, then press the “RST” (Reset) button, and after that the problem is fixed.

Thanks to him for finding the solution:

Test code

With this code, a blue LED should blink:

#define LED_BUILTIN 8

void setup() {
  // Initialize the serial port at 115200 baud
  Serial.begin(115200);
  while (!Serial) {
    ; // wait for the serial connection to be ready
  }

  // Configure the built-in LED (often GPIO 8 or 10 on ESP32-C3)
  pinMode(LED_BUILTIN, OUTPUT);

  Serial.println("ESP32-C3 prêt !");
}

void loop() {
  Serial.println("LED ON");
  digitalWrite(LED_BUILTIN, HIGH); // Turn the LED on
  delay(500);

  Serial.println("LED OFF");
  digitalWrite(LED_BUILTIN, LOW);  // Turn the LED off
  delay(500);
}
