    ACPI\ACPI0012 device identification ?




      Haswell motherboard(not Intels), windows7 OS.

      (I will ask motherboard manufacturer support - but maybe I'll get quick answer here )


      After updating to new uefi version, "Unknown device" appears which hardware ids are "ACPI\ACPI0012". All device drivers were fine before update(chipset, etc.), reinstalling chipset drivers didn't help. I suspect that this device could be because some new feature(xeon cpu feature?) was enabled after update.


      What device hardware id ACPI\ACPI0012 represents ?

      How do I find drivers for it ?
