We use it every day, but how does it really work? USB has been around for almost 30 years and it evolved into really universal interface that even extended from the world of computers into the world of extra low voltage electric distribution. In this talk, I will present the basic ideas of the interface with focus on physical layer.

We will cover:

- how the world of computer peripherals looked like before USB

- how did USB evolved

- how USB became the universal interface for delivering extra low voltage

- how the Type-C connector changed everything
