Tips

  • Use a known-good device (e.g. a flash drive) to test each port.
  • If a port doesn't react, try blowing out dust or testing with a different cable.
  • Charge-only ports (USB-C chargers on some laptops) may not trigger a connect event.
  • All detection runs locally in your browser — no data is sent anywhere.
