Finally, after
years of procrastination, I have gotten around to mocking up an additional rear panel USB port.
I used a short USB type A male to USB type A female header cord from Startech, combined with a low-profile PCI bracket.

Nobody sells low-profile USB PCI brackets, so I had to order a dual-port bracket and use a small washer to secure the second fastener.
The cable is
just long enough to route over the PCIe add-in cards to the type A header on the Blackbird board. I'm not sure how well (or not) this would have worked with a full sized system.

I tested that it is working and now finally have communication between my workstation and its uninterruptible power supply. Maybe I can start leaving this system powered on 24/7 once more.

Kudos, Raptor Computing Systems, your boards can survive
at least:
Power Cycles: 1,126
Power On Hours: 7,986
I hope the next ones are even better.
