USB is one of the most popular interfaces not only in PCs but also in cars! Linux kernel supports both host and device side of USB protocol. Many people use it but have no idea how it works and what are the consequences of its design.

During this talk Krzysztof will discuss practical aspects of USB protocol and its implementation in Linux. First part is a brief introduction to USB protocol. Then Krzysztof will explain basics of USB host implementation. Questions like "How new devices are being discovered?", "How drivers are selected?", "Why badUSB attack works so well?", should be answered in this part. The final step is going to be short description of device side implementation. "What is needed to build my own USB device?", "How to do this in Linux without writing kernel code?", all these questions should fit here along with suitable demos.
