Seems this was it.  After disabling power saving, there was no more
disconnects (I let it with power disabling for about two hours).
After re-enabling power saving, withing minutes there was an
disconnect/reconnect event.

Well, at least we now know the root cause of the problem that I
reported earlier with WUSB600N.
