First the log where it fails, done on a Dell C600 Inspiron laptop (I have
tested on a couple of much newer machines, too, in case you think this one
is too old, but with no different outcome):

Now similar lines from the log for the same camera, on a machine where the
camera is working properly:

The first log shows that the camera was sending packets okay; the
packets were just empty.  So it's not like the camera was failing to
work at all.  The second log was the same as the first except that the
packets were not empty; they contained data.

Indeed, this is suggestive of something like not having enough power.

Indeed, indeed. Except that being able to find a good AAA battery in the house and putting it in the camera did not help the camera to stream, at all. So it is something else.
