Abstract:
A hub hub control method, wherein the hub possesses an uplink port and a plurality of downlink ports, includes: receiving link status of each downlink port to know whether each downlink port has built a link; and when none of the plurality of downlink ports has built a link, controlling the uplink port to be unable to build a link. A hub control circuit, the hub possessing an uplink port and a plurality of downlink ports, includes a link status reception unit and an uplink port control unit for respective execution of the two steps of the hub control method.
