I have uploaded a sketch that transform my lilygo ESP32-S3 in a USB keyboard and mouse emulator
The sketch works, but I can't upload a new sketch as the serial port is then disabled.
How can I erase the sketch or upload a new sketch ?
Is it possible to have serial port and USB keyboard and mouse emulator at the same time ?
(It's possible with an ardunion leonardo)

#include "USB.h"
#include "USBHIDKeyboard.h"
#include "USBHIDMouse.h"

USBHIDKeyboard Keyboard;
USBHIDMouse Mouse;
uint8_t buf[200];
void setup() {
// open the serial port:
Serial.begin(115200);
// initialize control over the keyboard:
Keyboard.begin();
Mouse.begin();
USB.begin();
Keyboard._onGetDescriptor(buf);
}

void loop() {
// check for incoming serial data:
if (Serial.available() > 0) {

// read incoming serial data:
char inChar = Serial.read();
Serial.print(inChar);
// Type the next ASCII value from what you received:
Keyboard.press(inChar);
Keyboard.releaseAll();

}
Mouse.move(20, 20, 0, 0);
Keyboard.press('Q');
Keyboard.releaseAll();
delay(3000);
}
