Abstract
A system and method for detecting a USB cable-type. A USB PD device configured at a near end of a USB cable is configured to (i) receive and process a signal from a device at a far end of the USB cable to determine a power rating of the USB cable and (ii) adjustably establish power delivered by the first device to the USB cable as a function of the determined USB cable power rating.
