DYNAMIC FUNCTIONAL INPUT/OUTPUT (IO) DEVICE INTERFACE SELECTION THROUGH POWER STATE TRANSITIONS

In one embodiment, an apparatus includes interconnect circuitry to implement one or more layers of a Universal Serial Bus (USB)-based protocol. The interconnect circuitry can implement a first USB-based interface and a second USB-based interface. The apparatus further includes telemetry circuitry to generate telemetry data, cause the telemetry data to be transmitted via the first USB-based interface, detect a power state transition in the apparatus, cause the telemetry data to be buffered based on detecting the power state transition, and cause the buffered telemetry data to be transmitted via the second USB-interface based on a set interface request indicating the second USB-interface.
