USB is not tied to anything specific so that could well be the case. Another interest of mine is CNC machining (mill conversion and looking at a Chinese laser) using MACH3 software. People have tried everything to get the motors to run from a USB connection as machines with parallel ports are getting rare. No success at all. A couple of companies are using an Ethernet connection from the host computer to their own CPU board (https://www.poscope.com/) - this works great. USB no.
