BUS RELAY APPARATUS, INTEGRATED CIRCUIT APPARATUS, CABLE, CONNECTOR, ELECTRONIC APPLIANCE, AND BUS RELAY METHOD

摘要

A bus relay apparatus includes: an upstream port unit to which a USB host is connected; a downstream port unit to which a USB device is connected; an upstream port control unit; a downstream port control unit; and a relay unit configured to relay a packet transferred between the upstream port unit and the downstream port unit. In the bus relay apparatus, the downstream port unit reproduces a bus status detected by the upstream port unit and transmits the bus status, and the upstream port unit reproduces a bus status detected by the downstream port unit and transmits the bus status.
