I received it yesterday and connected it today using 5 volt on the "vcc"
pinc (just wanted to make sure), and it was detected without any kind of
problem.   After that I switched to providing 3.3 volt to the "3.3" pin
(bypassing the voltage regulator), and it again detected.    Phew.   I did
not blow anything up after all. :-)

After that I took a look at the old sensor using a magnifier to see if I
could perhaps spot a mis-solder.  Only than I noticed that it had, somewhere
between now and two days back, lost its cap (with the tiny hole in it) ...
I did not bother looking any further, and tossed it.
