Title:

SYSTEM EVENTS IN UNIVERSAL SERIAL BUS (USB) POWER DELIVERY DEVICES

Document Type and Number:

WIPO Patent Application WO/2017/143471

Kind Code:

A1

Abstract:

Techniques relating to communicating system events in universal serial bus (USB) power delivery (PD) devices are described. In an example, a USB PD controller receives a notification of a system event in a first device associated with the USB PD controller, the system event being based on one of a change in machine state of the first device and occurrence of a user interaction event in the first device. A PD protocol based message, indicative of the system event in the first device, is generated. The PD protocol based message provides for activation of a predefined profile setting in a second device, wherein the second device is to interface with the first device through the USB PD controller.
