Solved: I'm a bit embarrassed but I have a defense. First, my defense <g>. I've been around for a while and even though I may not be current on my tech, driver
installation habits die hard. I make it a point to point devices at drivers
via device manager rather than point a driver install or setup at my system. In the past this ensured I didn't get extra stuff and was rarely a problem.
In this case I pointed all device candidates at the USB driver package and came up with the three hubs but no roots. Not surprisingly, the three unknown devices were my three roots but I couldn't point them at anything -- driver update wasn't an option.
So, the solution was to run the driver setup and get out of the way. Let me know if I owe anybody beer money for time spent
Thank you sincerely.
