    Default 7730 USB disconnects

    When I connect laptop to 7730 as soon as I crank engine it disconnects and gives usb failure. Then engine won’t rev up.
    I have changed cables

    You also tried different USB port on your computer?

    With the computer disconnected will the engine start up?
