I connect the program box to the pc via a USB cable (admittedly a Nokia phone one not that I think that should make ant difference?) & the display very faintly displays "USB connected to PC!" when I then connect the box to the ESC with the extra cable having ensured that the -,+ & S are connected like to like the power buttn flashes red a couple of times then green rapidly for maybe 1 second before reverting to green flashing every couple of seconds. However as soon as I connect the ESC the display on the box goes blank.
