It could be the physical ports themselves.  I have my desktop system in
a 15+ year old case.  As of a few years ago, the front USB ports got to
the point where the number of devices they could not recognize (I would
get the same log messages) annoyed me enough that I got 3.5" front panel
with 2 USB 3.0 connectors and gave up the empty bay for that panel.  I
suspect a combination of physical age and protocol age (they might even
be pre-2.0) is the cause of the problem in my case.

I will sometimes still use the old ports and when they have a problem I
switch to the new ports, which have not yet encountered a problem
recognizing a device.
