I have (maybe, nearly) the same problem and tried everything a man can
try on this planet. But nothing helped, so i've bought another kind of
USB stick for replacement. After a month the Cruzer apperared in my hand
and i gave it a chance, put it into the hole. And now it works as in the
old days, without any known reason. The only thing i can imagine that
one of the Windows Updates (WU) corrected the problem caused by a
previous WU. BTW after the many experiments this was my suspicion that
the misterious problem is because of a WU and this is why i can't solve it.
So, get all of the possible WUs and try again. If it doesn't help, i
have no other clue.
Bye.
