    Hi David,

    Thanks for point out it, I have miss it.

    BTW, did we verified Modern standby support of the TUSB3410 on intel platform in previous?  (demo board or customers usage)

    Thanks,

    Please see this doc. 

    . 

    A common example is the USB host controller. The USB host controller can power down only after all of the USB devices connected to it have entered a selective suspend state. If a USB host controller has a USB mouse and keyboard connected, the host controller can power down only after both the mouse and keyboard have powered down. If either the mouse or the keyboard stays powered on, the USB host controller also stays powered on.

    All host controllers on the SoC must power down for sleep in order for the SoC itself to power down. This is why it is critical that every device perform device power management. The SoC itself can only power down when each host controller has powered down. The host controllers can power down only after all devices connected to them have powered down.

    To me, this is a USB host controller functionality to make sure the TUSB3410 goes into SUSPEND state.

    Thanks
