We are using the CY7C65632-TQFP48 (4-port hub), In this hub data sheet given as each down stream port power controlled by PWR#(port power pins) When the hub is configured, the ports are not driven and the host may power the ports by sending a SetPortPower command for each port. But default hub is configured and 4-port are working and how to send the SetPortPower command to hub to control the down stream ports (use set port power command is given in datasheet).
