> Any cable that can transfer data faster than USB 2.0 speeds also requires a chip to do so.

I always found this confusing because USB 3.0 Micro-B cables can transfer data faster than USB 2.0 without needing an e-marker, so why do USB-C cables need one if they already have the Tx and Rx SuperSpeed wires?

It seems like the answer is, roughly, "it's complicated".
