There even are some which are power only, no data. The pins simply
aren't wired. But one would notice this pretty quick, I think.

Regardless, my mobileread anecdote? The bad cable? Was new, recently
out of the wrapper. Like Mark says, you can't tell by eyeball, or by
age. Brand can reflect general build quality but is no guarantee that
any given cable is going to work properly.

I think it's less that they are electrically bad per se. I think it's
more about electrical noise coming off the system board, or even the
connected devices themselves especially if they have external power.
Some cables are more susceptible, or become more susceptible with use
(plugging, flexing), than others. Is my guess.
