An upstream facing port device (UFP device) and a downstream facing port device (DFP device) allow a host device and a USB device to conduct SuperSpeed communication via a non-USB compliant extension medium. In some embodiments, the UFP device helps overcome increased latency by generating synthetic packets to be transmitted to the DFP device in order to pre-fetch more data packets from the USB device than requested by the host device. In some embodiments, the DFP device adjusts service interval timing or caches data packets from the host device in order to compensate for the increased latency. In some embodiments, the DFP device transmits a synthetic acknowledgement packet to the UFP device to indicate a larger amount of free buffer space than is present on the USB device to help overcome the increased latency.

Aspects of the embodiments are directed to systems and methods for performing link training using stored and retrieved equalization parameters obtained from a previous equalization procedure. As part of a link training sequence, links interconnecting an upstream port with a downstream port and with any intervening retimers, can undergo an equalization procedure. The equalization parameter values from each system component, including the upstream port, downstream port, and retimer(s) can be stored in a nonvolatile memory. During a subsequent link training process, the equalization parameter values stored in the nonvolatile memory can be written to registers associated with the upstream port, downstream port, and retimer(s) to be used to operate the interconnecting links. The equalization parameter values can be used instead of performing a new equalization procedure or can be used as a starting point to reduce latency associated with equalization procedures.
