Abstract
Devices and methods for generating timing signals at a rate that matches a rate of remotely generated timing signals are provided. In some embodiments, a host generates timing signals in accordance with a USB specification, such as keep-alives, start-of-frame packets, or ITPs. An upstream facing port transmits the timing signals over a network to a downstream facing port. The downstream facing port generates and transmits timing signals to a USB device at a predetermined rate, and alters the predetermined rate based on an analysis of the rate at which timing signals are received from the upstream facing port.
