I think it is a good question how to test for backfeeding safely. If it were me, I'd unplug the usual power supply from the Pi and then plug the powered hub in to see whether the Pi tries to boot. Maybe I'd use an older Pi for this. If anyone has a better idea, it would be nice to know.Ok, so I will be safe as long as I don't connect a power supply? Then the question remains how to test the hub for backfeeding when a power supply is connected.Back feeding can occur if you have a separate power supply connected to the hub. If the hub is bus powered then back feeding will not occur.Does backfeeding only apply to powered USB hubs or can it happen when powereing it from the USB bus?
