Note: The Facedancer is no longer being manufactured by us. We recommend anyone looking at the facedancer21 to see the Cynthion device which has additional capabilities than the facedancer.
The Facedancer is an open-source USB emulator and fuzzer.
Unlike the general-purpose GoodFET boards, the only purpose of this board is to allow USB devices to be written in host-side Python, so that one workstation can fuzz-test the USB device drivers of another host.
