For the archives regarding problematic USB disconnections: I can't
remember if I've ever said this on this list. I've intended to so it
may be sitting in a draft email somewhere...

When other explanations don't fit and it's about laptops, the
unexplained disconnection can be about *heat* from the laptop's fan
exhaust. Well, depending on a desktop PC's layout, it could be for the
same reason there, too.

That was an accidental find of mine. I was having trouble with an
external hard drive doing the same disconnect game. It wasn't doing
that when plugged into the ports on the other side of the laptop.

One day I realized how HOT the affected USB connection was when I
reached up to unplug and replug while still thinking a loose or
degrading connection was the problem.

I blocked the fan's heat exhaust somehow, redirected that heat and
never had a disconnect problem again on that same port. That was, yes,
permanent success while still using that same external hard drive's
dock. In fact am STILL using that same dock ~five years later. :)

PS No, modules never played a part in that particular experience.
