Can a Raspberry Pi be powered via one of its USB data ports? Does it depend on whether the Pi is the lower powered Model A or a Model B? No other USB devices would be plugged directly in to the Pi but the onboard Ethernet would be used.
I have ordered a powered USB hub with the intention of using it to connect the Pi to a number of other devices. It hasn't arrived yet but I wondered if it would at least be safe enough to try to power the Pi via one of its USB ports. Anyone tried this?
