It looks like switching to another USB port on my machine fixed the
problem.  It has been several days now, and I haven't experienced any
trouble with the keyboard at all.  Now why didn't I think of trying a
different USB port earlier?  Probably because I was searching for _some_
use for those old USB 1.0 ports on the machine.  Maybe I'll get one of
those USB foot warmers, or maybe some USB LED indicators.

This brings up another topic:  What makes a good USB cable?  I pick up
USB cables from the local computer surplus store for a couple of bucks
each (living in California's Silicon Valley is great for cheap computer
parts).  The cables certainly seem to be the same quality as those
costing several times more.  I've never had any problems, but I hear
lots of chatter about "bad" or "cheap" USB cables causing problems.  Are
bad cables really all that common?  What makes a good cable?  How about
USB "extension" cables?  Are they permitted under the official USB spec?
Do they often cause problems?

Thanks for all your help troubleshooting this, Alan.

Happy holidays.

Cheers.
