I guess the question can be turned in: what does OpenBSD under the wood to avoid uaudio0 or ugen1 get transformed in a nice passage to hack my whole system? Eg. I know some of us go around with OpenBSD on usb sticks but our equipment on the desk is safe from usb tools like eg. micro usb equipment inserted in our usb hub? What countermeasure OpenBSD have to these kind of physical penetrations using the usb stack? Finally are uaudio but mainly ugen stress tested to avoid that? Great question indeed, Lucretia!
