Composite USB Gadgets on the Raspberry Pi Zero

Hi, Hackaday! 😀

Want your Pi Zero to emulate a keyboard, ethernet adapter, serial device, mass storage, and many more at the same time? This tutorial is for you!

The Pi Zero is all the rage – and I too am working on a Zero-based project.
[LadyAda] and [gbaman] both have written tutorials on the old series of drivers, g_{hid,ether,serial,*}. Those are not flexible at all, only allow for one loaded at each time and in case of the hid-gadget even require you to modify and recompile the kernel module.

LibComposite solves those problems by putting the configuration into userland (ConfigFS).
