2017-02-01 Note: Facedancers went out of stock today. The next manufacturing is still in progress and we expect to have inventory again in March. If you order now you will reserve your unit from that batch.
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.
