    DATA, it’s legacy (1.0-2.0) USB’s differential pair for backwards compatibility. You only need one side to make contact so they decided to simplify plugs for devices that use the legacy mode. For example most mice and keyboards, even ones with USB-C, still use USB 1.1 because they don’t need the extra speed, and 1.1 cables are cheaper because the low speed allows them to be unshielded and still not suffer much interference.

    USB has been plagued by many weird decisions and scope creep but I really hope USB-C puts an end to that. A fully wired cable contains enough twisted pairs for just about any application and the physical properties are great. Too bad manufacturers will keep creating non-compliant devices such as naïve hubs that don’t account for PD voltage mismatch, or cables/chargers that claim to do something and actually don’t, making it a coin toss as to what devices they work with.
