USB is one of the most popular interfaces in both PCs and mobile devices. Linux kernel supports both host and device side of USB communication. Writing kernel code is known to be difficult and time consuming. Thanks to libusb, libusbg and FunctionFS it is possible to create own, custom USB devices just in userspace!

The goal of this tutorial is to show that creating own USB device on Linux board and writing host driver for it can be both fast and easy. In the first step Krzysztof is going to do a brief introduction to USB protocol and its support in Linux environment. Second part is USB gadget composition using ConfigFS/libusbg. Next step is introduction to libusb and writing a simple userspace driver for some custom USB device. The final step is implementing own USB function using FunctionFS and putting all parts together.
