SIDE NOTE:

In an attempt at assessing which of the two is most useful for my needs, I
was monitoring USB comings and goings using the Nirsoft USBDeview utility
Poutnik suggested alongside the Sieber USBTreeView utility Paul suggested.

My goal was to use them for a day or two, and choose the one I like best.

On one monitor I had both Nirsoft USBDeview & Sieber USBTreeView running,
and wouldn't you know it. At some point in time, I heard the classic USB
disconnect and then re-connect sounds, and glanced at the USB viewers.

In Paul's suggested Sieber USBTreeView, the line for the USB mouse was
green, and no other line seemed highlighted. So it's the USB mouse!

Note: At first, I only saw the green because I missed the red, but when I
tested it by pulling out the cord, it goes red first and then green when
reconnected and then within a second or so, it goes back to transparent.

That's a neat hardware debugging tool for intermittent USB disconnects!

Given that works so well, if you have an intermittent issue with USB
devices disconnecting momentarily, then I would suggest keeping Paul's
suggested Sieber USBTreeView running, so that, when it happens, you can
visually see which device is disconnecting and then reconnecting.
