WHCK USB device connection S3+S4 failed RRS feed

  • Question

  • Hi,

    When I run this item, the test is failed before the client enter S3 or S4 power state.

    No matter I connect my device through a USB 2.0 hub to the client EHCI or xHCI port, both get the NG log as below :

    Warning : Only root hubs detected downstream of xHCI

    Device instance path not found ,trying VID/PID match

    Error: Terminating: USB Device not found on xHCI or any testable embedded configuration, please re-test in another configuration 

    By the way, I found either I connect through EHCI or xHCI port , my device is always under EHCI controller. That may be the cause of "USB Device not found on xHCI or any testable embedded configuration". But I don't know how to let my device under the xHCI controller.

    Could anyone give me a debug suggestion ?

    Thanks.
