Interesting.. could you try to forcefully shut down L5A (I doubt you'll be able to do so with L1A given it powers so much digital logic), or set its regulator-min&max-microvolt to a way-too-low voltage (vmin seems to be 312000)? You should then be able to tell fairly easily, depending on whether usb2 still works after a replug Konrad
