    Hi Eileen:

        There are couple of ways to force hub to low power mode.

    1: if on PC or laptop, set system into sleep mode or hibernate  mode.

    2: remove downstream port  device, hub will be in suspend mode.

    3: remove voltage on USB_VBus pin, hub will be disconnected.

    4: for hub into suspend mode with usb command.

    Best
