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.

Dynamically influencing bandwidth

In one embodiment, an apparatus includes a host controller to implement one or more layers of a Universal Serial Bus (USB)-based protocol to provide an interconnect for a plurality of devices. The host controller is to monitor control plane messages on the interconnect, detect, in the control plane messages, a power state change command for a device coupled to the interconnect, wherein the devices utilizes a tunneled protocol on the interconnect, and modify power distribution for one or more other devices of the interconnect based on detecting the power state change command.
