Estimating the term…
Universal Serial Bus (USB) cable type detection and control techniques are disclosed. In an exemplary aspect, a device connected to a cable detects whether the cable is a legacy cable (i.e., a Type-A to Type-C cable). If the cable is a legacy cable, the device determines an appropriate current to draw based on whether the cable is compliant with the USB Type-C specification or non-compliant. Additional exemplary aspects of the present disclosure determine whether a connector adaptor has been put on a legacy cable and determines an appropriate current to draw based on the capabilities of the legacy cable. Still further aspects of the present disclosure evaluate not only the cable to see if the cable limits the current draw, but also evaluate a device at a distal end of the cable to verify if and how current may be drawn by such remote device from a mobile terminal.
