Hardware Defined Byte

I would like to make a PCB that sends a specific byte of information through a usb connection. I need the PCB to be as small and simple as possible to fit into a nice thin housing. Simply put there would be a push button that would send a byte of information identifying it had been pushed, without a micro-controller. Is there a way to specify a sequence of on-off 1-0 within the circuitry on the PCB? namely a byte. I've searched EVERYWHERE and haven't found anything relevant.
