USB, unfortunately "comes and goes" with the PC often "going away" from the interface for as much as half a minute, or perhaps more...

I can't say that I have seen any long pauses in the USB communication.

Neither have I!

But Richard often mentions it - so I guess there must be some fault(s) with his PC(s) and/or the particular USB device(s) and/or Driver(s) that he's using...?

Using PC's for useful work is becoming increasingly difficult, as the PC drifts in the direction of the MAC, focused on entertainment rather than computing. Entertainment is a vital goal, but compromising the other useful characteristics of an otherwise powerful vehicle just to promote gaming, audio/video distribution, and communication is, IMHO, terribly shortsighted.

But, if these "entertainment" applications suffered long pauses as described, they would be absolutely unusable!

So it really can't be anything inherent in either the PC itself, or USB itself - there must be something dodgy in Richard's setup(s).

But it is certainly the case that some USB implementations on the PC are extremely poor...
