Meet Cynthion, the all-in-one USB multi-tool from Great Scott Gadgets for analysing, developing, and experimenting with USB. It captures and inspects live USB traffic, then pivots to device creation and research with the same compact, FPGA-based hardware.
Use it on the bench to debug enumeration issues, validate peripherals, or teach core USB concepts. With open-source tooling like Packetry, LUNA gateware, and Facedancer libraries, you can move from passive protocol analysis to active device emulation and security exploration with confidence.
