In providing USB communication functionality over a non-USB-compliant extension medium, increased latency and processing delays may be introduced, including during configuration of endpoints. In some embodiments of the present disclosure, an upstream facing port device (UFP device) and a downstream facing port device (DFP device) are used to extend USB communication across an extension medium. In some embodiments, the UFP device extracts information from packets sent between a host device and a USB device during configuration of an endpoint. In some embodiments, the UFP device sends a synthetic NRDY packet to the host device in response to a STATUS Transaction Packet to provide the UFP device and DFP device additional time to complete configuration for servicing the endpoint.
