> 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".

If you’re following USB-C standard, all cables with faster data than 480mbps and more power than 60W require an e marker, period. Whether devices will still function for USB3 without that marker… that’s another story and will depend on the device.
