Quite frankly, that is a drastic step to take. Many people, like
myself, need a USB port(s).

What I find so annoying is that this bug did not exist prior to version
12.x; therefore, it is obvious that something changed. I am not a
highly skilled system programmer, so my chances of discovering the
problem are at best nil. However, the person or persons who wrote the
code should be aware of what has changed and either revert it to it
former working condition or fix it in its present state.

This situation has gone on for over a year and continued through two
major versions. That is just not acceptable.

Perhaps, if we could collect a list of the know systems that are
affected by this bug, it might help the developers to discover the
source of the problem.

My System:

Dell XPS 8930
32 GB DDR4 @ 2400MHz
9th Gen Intel Core i3-9 100 (4 core, 6MB Cache)
