In case you have any issues configuring your board, you can try the following:
- Make sure you are using a Data USB cable
- Try pressing the reset button on the board before starting the "Add device" routine.
- Try doing a quick double tap of the reset button to get the board to bootloader mode.
- If you are using a USB Hub for connection, try directly connecting the board to the computer.
- Make sure that there is no other IDE or Web editor open in your computer.
