    <thetext>Some powered USB hubs feed power to the MinnowMax back through the USB port. This does not cause the MinnowMax to power on. However if it&apos;s already powered on, removing the MinnowMax&apos;s power adapter will not cause it to shut down. Instead, it will continue running happily on power from the USB hub. This works with either the USB 2 or USB 3 port.

I have no idea how it would behave if some load were placed on the MinnowMax-- perhaps forcing the CPU into a higher clock/power state would cause it to run out of power and reset.

This was with a dual-core A0 board, although A1s probably have the same problem.

The specific USB hub tested was this one:
