摘要： A Universal Serial Bus 4 (USB4) host system for tunneling USB2 data includes a USB controller and a first routing circuit communicatively coupled to the USB controller. The first routing circuit is to configure a downstream tunneled path between the USB controller and a second routing circuit. The first routing circuit is further to packetize outgoing USB2 data received from the USB controller into a first plurality of USB4 tunneled packets. The first routing circuit is further to encode the first plurality of USB4 tunneled packets for transmission to the second routing circuit via the downstream tunneled path, to initiate processing of the outgoing USB2 data by a USB2 device associated with the second routing circuit.

摘要： Universal Serial Bus (USB) Power Delivery is augmented by allowing devices that attach to the USB to include and/or have access to an enhanced device policy manager (eDPM) so that device information such as status, state, or requirements, such as power requirements, may be at least be shared by the eDPMs between, for example, a host device on the bus, a secondary device providing power to devices on the bus, and a new device attaching to the bus. Sharing device information facilitates the host having contextual awareness for the attaching device and assists with determining whether the attaching device may be enumerated on the bus. If not, such as due to insufficient power available from the secondary device, the host and/or secondary device may seek to influence bus devices to change an operating mode to accommodate the attaching device.

摘要： Buses such as USB4 or Thunderbolt 4 buses may allow for device combinations that actually cannot be accommodated on the bus. A monitoring component, e.g., software and/or hardware component, such as an Operating System (OS) policy manager, may monitor a bus for events identifying changes to devices on the bus. The monitoring component may influence mode changes to hardware/software, such as to the USB configuration, device driver settings, attached device settings, and/or settings for devices attaching to the bus. Influenced changes facilitate accommodating changes to the devices attached to the bus. For example, if a display is attached and it would exceed available bus bandwidth, cause an excess system load, or cause some other problem, rather than fail to enumerate the display, instead hardware and/or software associated with the bus may be influenced to result in a resolution reduction for the display to accommodate it attaching to the bus.
