I don't remember, but I can find out.
Actually there is sometimes a good reason. For
example, an iPhone
can pull far more current than USB guarantees (well over an amp), so
it tests first.
That makes sense - provided it scales back to the standard max if the
magic indicator isn't present. Refusing to charge at all, I can't see
that as anything but customer lock-in.
