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.
