    NUC5i3RY*: Bug in BIOS Version RYBDWi35.86A.0249.2015.0529.1640

    nuc5i3-user

      Hi,

       

      I have a NUC5i3RYH with latest BIOS version and I've disabled the CIR receiver in BIOS setup. However, after resuming from S3 (hybrid standby and S4 are disabled in Win 8.1 Pro and Intel® Ready Mode Technology is NOT enabled/used) Device Manager shows an unknown device with following ID:

       

      ACPI\PNP0530\0

       

      There is no driver for this device and it doesn't matter if CIR was previously enabled in BIOS setup and the Nuvoton driver installed in Win 8.1. If you reboot the system, the unknown device is not visible until putting system in S3 sleep mode and then resuming.

       

      I think, this is a bug because the disabled CIR is still somehow visible to the OS. When CIR is enabled, its hardware ID is very similar:

       

      ACPI\NTN0530\0


      Thanks.
