Moreover, for loading at the same, time, I'll get into a small modification of the circuit, with a button to disable the hub as long as the function load starts, then release the button to activate the hub (by cutting 'supply controller for example).
By cons, quality, not great. very poor quality plastic, taken from male through and too long, no USB logo on it (so do not follow the USB charter). But hey, at least the hub is working properly.
