I'll bite, systemd and its interaction with udev is beyond my paygrade.
How do I investigate this?

Not sure I have any. I tried two different USB 3.0 connectors with the same 
result.

Is there any way I can test this?

I just checked my C922 it's plugged into a USB2 port and works fine

Try ANY usb device in your ports and see if it shows up in lsusb

You may have a bad port
