My larger goal is to be able to play the PS4 while recording the inputs for later analysis.

Yeah, it won't work with a PC in some regular mode; you need to
essentially switch off your USB subsystem to _not_ attempt to talk to
plugged in devices, then watch what goes over the stream. I doubt that
regular USB systems on PCs allow for that. This is essentially
something what you want to do with a USB analyzer.
