Abstract
A system and method of conducting precision time management in a universal serial bus system with a retimer. The method includes initiating, from the retimer, a link delay management request on an upstream-facing port of the retimer. The method further includes receiving, at a downstream-facing port of the retimer, a link delay management request and responding to the request received on the downstream-facing port.
