[Lab] Launch Pad

[Jean-Marc LeBlanc]

well since it is not bidirectional communications on the wire, one
could wire it with a transistor very simply and a voltage divider but
that would require a 5V power.  The schematics though claim that test
point 1 (tp1 on the board) is the USB-Vcc and test point 3 (tp3 on the
board) is the USB-Ground
