A race internal to libusbx itself? Sounds undesirable. If I continue to use IOServiceAddMatchingNotification() myself, but don't actually call into libusbx as a response, that should be fine, yes? In fact, I don't actually use libusbx directly at all, I use this, which in turn uses libusbx: <https://github.com/labjack/exodriver> Sounds like it may need updating for 1.2. Is this hotplug API opt-in? libusbx won't start observing the comings and goings of all USB devices by default I hope?
