Systemd unit for managing USB gadgets @Raspberry_Pi #PiDay #RaspberryPi

Super handy post by by Lars Kellogg-Stedman up on Odd Bits.

The Pi Zero (and Zero W) have support for acting as a USB gadget: that means that they can be configured to act as a USB device — like a serial port, an ethernet interface, a mass storage device, etc.

There are two different ways of configuring this support. The first only allows you to configure a single type of gadget at a time, and boils down to:

Enable the dwc2 overlay in /boot/config.txt
Reboot.
modprobe g_serial
This process is more fully documented here.

The second mechanism makes use of the libcomposite driver to create multifunction gadgets. The manual procedure is documented in the kernel documentation. While it’s a useful feature, the configuration process requires several steps and if you only do it infrequently it can be easy to forget.
