    Hi Henry,

    The TUSB8041 is a self-powered hub, so it cannot be entirely powered off by a USB command. It can be put into low power mode by the USB host if both the USB 2.0 and USB 3.0 buses are put in suspend / U3. Also, the hub's downstream ports can be powered off by the a command from the USB host as you noted above.
