Does 6400 USB Power Off indicate shutdown is complete?

On shutdown, I'd like to use the Flex's USB to signal when to shut off the 12V DC power supply in a remote setup. In other words, when the remote user turns off the REM_ON, the 12V DC power supply stays on until USB power is turned off. The reason to do this is that the power supply is less likely to be damaged by power line surges, as well as save a little energy. Does the USB turn off only after the Flex 6400 has adequately shut down?

    The engineering team does not monitor this group at all as they are focussed on other issues.

    I opened a support ticket for you. You could also use a voltmeter to measure it.
