Abstract: A method and system for managing power for Universal Serial Bus (USB) ports, in particular USB Type-C ports that are connected to USB devices that do not support USB power delivery (USB PD). The method and system present an advertisement of a default power supply to a USB device, receive power attribute information from a USB device configuration descriptor during USB device enumeration, in response to the connecting USB device not supporting USB power deliver (USB PD), and dynamically change the power supply to meet the power requirements of the connecting USB device identified by the power attribute information.

Abstract: A device including a transceiver to support asymmetrical full duplex communication across a connected medium. The transceiver including a transmission circuit to receive a transmission input and transmit the transmission input via a SuperSpeed data driver and a low frequency periodic signal (LFPS) transmitter over the connected medium, and a receiver circuit coupled to transmission circuit, the receiver circuit to filter a received signal from the connected medium through a low pass filter to an LFPS receiver.

Abstract: Described is an apparatus comprising a first circuitry and a second circuitry. The first circuitry may be operable to provide output to a unidirectional data path for carrying a packetized data stream. The second circuitry may be operable to provide output to, and obtain input from, a bidirectional control path for carrying a packetized control stream. The packetized data stream may comprise pixel data traffic and frame-synchronous metadata traffic, and the packetized control stream may comprise frame-asynchronous metadata traffic and control traffic.

Abstract: A method and a device to participate in a managed Universal Serial Bus (USB) ecosystem. The method including establishing a connection with a plurality of devices in the ecosystem as a many-to-many relationship between extended USB device policy managers, and coordinating power and data exchange within the plurality of devices the ecosystem including at least one device that is not directly connected.
