There was no other choice but to do another hard shutdown. Booting having completed, there was still no USB communication to the wired keyboard and mouse. After waiting two minutes before powering up again, The Pi was powered up. This forced me to do a hard shutdown, hoping my SD Card would not become corrupted by doing that.

I removed a wifi dongle (Panda PAU06), that I use for its better range, and I also removed the Logitech wireless keyboard dongle, and plugged in a wired keyboard and mouse into the USB 2 ports. After a proper reboot, the USB ports were unresponsive. The familiar debian (Buster) sudo apt update and sudo apt upgrade that I did 45 minutes ago, 1-21-2020 18:25 UTC, did not report any errors. The purposed usefulness of this post is the hope that there is a way to get my wireless keyboards working with this system again, and, to help others see the sort of troubleshooting steps taken to arrive at a final conclusion. This upgrade did do an rpikernelhack, if that info helps.

See my answer post somewhere below this OP. There is still an impression that the eeprom-image update is an option, since this eeprom update install does not happen automatically with the typical sudo apt update and sudo apt upgrade, but my experience concludes that it ought not be presented any longer as an option, but as a requirement, clearly, that currently must be done explicitly by any user of an older Pi4B, at least as of this writing (1-23-2020 18:50 UTC). Apparently the recent update/upgrade downloads (using apt) now require the temperature mitigating eeprom image for the Pi4 family, whereas previously, the impression I had was that it was an option for those who want to run the Pi4 a bit cooler without having to use a more aggressive heat sink fan combination.
