Code stopped if I remove the USB

[esportsim]

Hi, my simple code stops if I remove the USB from the PC. Why?

include

unsigned long previousMillis = 0; unsigned long currentMillis;

unsigned long serialCurrentMillis; unsigned long serialPreviousMillis; boolean is_working_led_on = true; int led_interval = 200; int working_led = 3;

Joystick_ Joystick(JOYSTICK_DEFAULT_REPORT_ID, JOYSTICK_TYPE_GAMEPAD, 128, 0, true, true, false, false, false, false, false, false, false, false, false);

void setup() { pinMode(working_led, OUTPUT); Joystick.begin(); }

void loop() {

// WORKING LED ---------------------------------------------------------------- currentMillis = millis();

if (currentMillis - previousMillis >= led_interval) { previousMillis = currentMillis; if (is_working_led_on) { digitalWrite(working_led, LOW); is_working_led_on = false; } else { digitalWrite(working_led, HIGH); is_working_led_on = true; } }

Joystick.setButton(0, 1);
Joystick.setButton(1, 1);

}

Probably because the sketch doesn't receive a response from the computer to the Joystick.setButton statements.
