You should follow this simple set of instructions. Firstly, make sure that the USB cable is connected, for testing you should only use the cable that came with the board, no extensions. Check that the server is installed and running (the green hand on your desktop and in the system tray) This should turn green when connected. Check to see what colour the light is flashing on the board, a red/blue light is looking for a connection, a red light means that there is power and a blue light shows that there is activity on the board.
