But if I was to plug a powered USB hub into one of the USB connections, would that give power to anything I plugged into that? If so, I could plug in multiple webcams in to that. The USB C to Ethernet/USB C isn't powered, so I can't add any more power to the USB connections. Is this an issue that affects the latest MBPs? What CraigS said about there being a limit to the bus power in the latest MBP. I've wondered whether there was a limit to how many USB powered devices I could use at the same time. I've had a few issues getting both my webcams (Logitech C920s) and USB microphone all connected.
