1. A computing device configurable to provide a downstream facing port (DFP) for allowing a USB device to communicate with a host via an upstream facing port (UFP), wherein the DFP is configured to:

  • receive a request packet via a non-USB communication channel;

    transmit the request packet via a USB-compliant communication channel to the USB device;

    receive a data packet from the USB device;

    transmit the data packet via the non-USB communication channel;

    generate an acknowledgement packet and transmit the generated acknowledgement packet to the USB device that implicitly indicates that the data packet was received by the host when the DFP is configured in a first latency mode; and

    receive an acknowledgement packet from the UFP and transmit the received acknowledgement packet to the USB device that implicitly indicates that the data packet was received by the host when the DFP is configured in a second latency mode.
