I'm fortunate enough to have another Ubuntu box, so I ordered an
inexpensive PCI-E firewire card for it, which allowed me to test. On the
test box plugreport showed the set-top-box. The card came with a full-size
to mini-size firewire cable, which I connected to the other 1394 socket on
my original machine, and voila, plugreport on that machine showed the
set-top-box. So it seems that either the mini-size socket on my original
machine went bad, or the mini-to-mini cable went bad. I have no idea how
that can happen to things sitting there undisturbed, but there you have
it. So this is SOLVED.
