If the USB is removed you will only have the 3V from the coin cell left. You will need 5V from the USB to get 5V on the 5V pin, so if you are not connecting the USB to the computer, you will still need to have a 5V power supply connected to the USB cable.</p> <p>Best regards,<br />Stian</p><div style="clear:both;"></div>
