Great Scott Gadgets - Cynthion

Cynthion is an all-in-one tool for building, testing, monitoring, and experimenting with USB devices. Built around a unique FPGA-based architecture, Cynthion’s digital hardware can be fully customized to suit the application at hand. As a result, it can act as a no-compromise High-Speed USB protocol analyzer, a USB-hacking multi-tool, or a USB development platform.

Out-of-the-box, Cynthion acts as a USB protocol analyzer capable of capturing and analyzing traffic between a host and any Low-, Full-, or High-Speed (“USB 2.0”) USB device. It works seamlessly with our open-source ViewSB software, which translates captured USB traffic into a human-readable format. ViewSB runs on Linux, MacOS, Windows, and FreeBSD.

Combined with the Cynthion software and the FaceDancer libraries, Cynthion becomes a versatile USB-hacking and development tool. FaceDancer makes it quick and easy to create or tamper with real USB devices—not just emulations—even if you don’t have experience with digital-hardware design, HDL, or FPGA architecture!
