      Hi there

      Got the following:

      RPi Zero
      7 Port Powered USB Hub

      However, the Hub's power source is 5V 1000mA.

      Would I be able to power the Zero itself from the Hub? To avoid having to use an additional Wall Plug?

      Thanks in advance

      Andy

        The host in this case is the Pi and is the usb system's master, it controls and schedules all communications activities with peripherals (devices controlled by usb) as slaves responding to commands from the host. So if you power the Pi itself from the usb hub, it becomes a peripheral of itself, and even thinking about this is confusing so I can't imagine the Pi will like it much. But I haven't tried this myself, so who knows.
