    Full-featured USB-C 3.1 cables contain a full set of wires and are "electronically marked" : they contain a "eMarker" chip that responds to the USB Power Delivery Discover Identity command, a kind of vendor-defined message (VDM) sent over the configuration data channel (CC). Using this command, the cable reports its current capacities, maximum ...
