PPS output is only half the battle. You also have to get it into the system that needs it. A modem control signal on an old fashioned serial port (not USB) is the classic approach. Unfortunately, many modern systems, especially laptops, don't have serial ports. GPIO pins on things like a Raspberry Pi also work well. PPS over USB adds the USB polling interval to the error budget. It will probably work well enough if the goal is under 15 ms. -- These are my opinions.
