e.g. Mouse no longer works at this point.

Yes, this is quirk of Raspberry PI internal hardware design. USB port 1 is wired to control power on network (wifi+Ethernet), and USB port 2 is wired to control power on all remaining USB ports.

Does this mean that I can control ports 3,4,5 independently?

mvp commented 6 years ago

No, you cannot control ports 3,4,5 independently. Port 2 will alter state for all ports 2,3,4,5 at once.
