USB wake up support solution.

Dear Team,

My customer would like to implement a feature on their Type-A USB port.

They are looking for a solution that can meet below scenario.

The system connects with an USB2.0 key board.

When it is in S5, the end user can use keyboard to wake up the system.

Therefore, the keyboard should communicate with an USB controller first, then this USB controller would use GPIO to wake up the system.

Do we have such solution? Or do you have any other suggestion to support this kind of scenario?

  

  • Jim,

    This scenario is usually handled by the USB host controller driver enabling the keyboard / mouse for remote wake during the low power state. We do not have any USB controller that can be implemented upstream of a keyboard to generate a wake GPIO.
