If I am compelled to offer an yes/no answer, I'll still punt. Tim's was
being pejorative and frankly I'm a bit confused as to why you have
jumped on with him but so be it.

What Lamar didn't say is that the WD Passport is not a typical USB drive
but happens to be one that draws power in addition to transfer signal
via the USB bus and so the demands on the cable are clearly greater. As
it was pointed out in the first link, it is recommended to only use the
supplied cable so it is not entirely clear that just any USB 2.0 cable
would be sufficient at all.

Aren't you just the least bit troubled by the fact that this discussion
has gone on for greater than a day and only one anecdotal report of an
insufficient cable has appeared? And even that one is not a typical
device?

If the exception proves the rule, then clearly by your inference I would
be right but this discussion was never about right or wrong as I saw it
anyway...the thread started with Summerfield stating...

to which I replied...

and Tim proceeds to do technical specification dump on USB
specifications which I have no dispute with whatsoever except that my
real life experiences have mirrored that which I was told...a decent USB
cable should work for his standard USB 2.0 drive.

What your axe is here, I don't know but myself, I tire when hearing
people dump endless technical detail that has proved to be irrelevant in
my experiences.

Interestingly enough, every other technology that you tried to drag in
were significantly flawed and problematic in crossing boundary standards
but personally, I have not had problems with USB cables - period.
