This workshop serves as an introduction to the USB hacking topic in general and to Raw Gadget specifically.
Raw Gadget is a low-level interface for the Linux USB Gadget subsystem. Raw Gadget allows turning any Linux-based board (like a Raspberry Pi) into a USB hacking tool that can emulate and proxy USB devices (similar to the Facedancer boards).
The workshop gives an overview of the USB protocol, the Linux USB Gadget subsystem, and the Raw Gadget interface. The offered hands-on exercises include capturing and analyzing the communication of USB devices, emulating USB devices via Raw Gadget, and proxying USB devices via Raw Gadget and libusb to aid reverse engineering.
Note that you must bring and prepare your own hardware to attend the workshop: see the list in the workshop instructions.
