I want my Raspberry Pi Zero W to show up as an ethernet device to my iPad. It is doable. It's been proven to work.

The problem is in the details. After ensuring there is a usb0 device, I setup systemd-networkd. I know that the cable must support both power and data. I know that only the Power/Data USB port closer to the middle may be used. I know that the device supports UDC - USB Device Controller (which in turn supports the gadget mode (On the Go).

Requirements as I would guess:

  • Fixed address for the Pi
  • Pi is running a DHCP Server
  • Multicast DNS is on

What steps am I missing that Raspbian Jessie is apparently doing automatically?

/etc/systemd/network/10-usb0.network

networkctl

  • @jsotola Yes. The fact that networkctl yields a usb0 device indicates that the steps were successful. The guide stops there and does not go into networking details, but using Arch Linux, one needs those details.
