#GNU #Linux #Tutorial #Driver #DriverDevelopment Let's take a closer look at USB. In this series of tutorials we will learn how to implement an USB device on a microcontroller and interact with it over our GNU/Linux OS from user- and kernelspace. Sorry for the bad audio, I had a cold. In this video I talk about some theory of the Universal Serial Bus (USB). But you are better of reading 'USB in a nutshell'. This will give you a better overview and more details. You want to support my work?
