USB 1.1 OEM GPS device not detected under xHCI RRS feed

  • Question

  • I got a USB 1.1 OEM GPS device. It is already certified in Win7 and trying
    to certify in Win8.
    In Win8 all tests are passed except "HCK related" tests. Tests are failing
    saying that "Device should be connected behind xHCI".
    The problem is I can't see my device behind xHCI.
    I have got a Dell Desktop with xHCI controller, but only USB3.0 devices are
    listed under xHCI. But my device is always listed under "EHCI" controller.
    Also I tried TI 3.0 HUB and other USB 3.0 Superspeed HUB which are detected
    under xHCI. But again, if I connect my device to those USB3.0 HUBs, it
    still gets listed under EHCI.
    So I am really frustrated after chasing Dell to find a machine which gives
    direct xHCI ports w/o any logical mapping.
    So I couldn't certify on Win8 yet.(But I have tested and running Win7
    certified version of drivers w/o any issues)

    This leads to failure of following test cases

    OS: Win8 x64
    Tests failed:
    USB Topology Compatibility Test
    USB Descriptor Test
    USB Selective Suspend Test (xHCI)
    USB MS OS Descriptor Test (xHCI)
    USB Device Connection S3+S4

    NOTE: Not only my device, any USB 2.0 HID devices also not detected under xHCI

    Please help me here.
