It's purely an analog device. Presumably they used USB because the cables are cheap, shielded, and have enough conductors for what they needed. (Probably ground plus signal wires for two linear pots and a pressure sensor.)
I hope they designed it so it doesn't fry something if you connect it to a real usb device, but I'm not inclined to try it.
