Have you ever used a true bare metal board ? Something that only has an MCU for the boards main processor ? Such as PIC32, Cortex M0/0+, M3, M4, or an MSP430 ? It would not be hard to combine one, or multiples of these types of embedded devboards to even a regular PC. USB also does not have the be the medium of communication either. Communication could be done over ethernet, wifi, bluetooth, *or* USB and remain practical.
