Hi, I am attempting to complete Stage 10 Step 7. When I connect the control board to the computer USB port, I don't get any lights and the port doesn't show up in Arduino. I have tried 2 different computers, I have also tried connecting directly with the blue cable into the control board, rather than through the extension cable. With the same result. No lights showing. Directly connected and no lights. If anyone has any ideas I would appreciate trying them.
