The Ducky’s LEDs are programmed to provide feedback to the user:
- A flashing GREEN LED means the computer and USB Rubber Ducky are talking to each other.
- A flashing RED LED means the USB Rubber Ducky can’t read the micro-SD card.
If you did not notice any LEDs:
- Sometimes, the host OS is a bit slow and misses the USB Rubber Ducky’s commands while it is enumerating the device. Try adding DELAY 3000 to the beginning of your payload.
