Asking Windows to check the driver and install the correct/latest one

Deleting the driver totally and then
removing/reconnecting the USB end
of the interface cable got it to find the correct driver. So at least
I can talk to my device programmers, etc, again.
That is EXACTLY what I mean by "full re-instaall"
Quite why the software decided to replace that driver
for me without
telling me is a mystery. Needless to say I am not going to run it
again.
perhaps an assumption that one would never have ANY other USB item
connected other than it?
Or "upgrading" some lower level part of the USB interface?
Long ago, I
learned, the hard way, that I should always make a complete
backup, or at least a restore point, before installing anything new, or
making any change.
I wish that I would remember to apply that lesson more consistently.
