Fatal1ty Z77 Professional Unknown device (missing ACPI driver?)

[Jamenetic]

I just built a new system using Windows 7 64-bit using the new Fatal1ty Z77 Professional board. Setup went smoothly, but there is one minor concern which I can't seem to fix. Under Device Manager there is an "Unknown device" flagged that I can't seem to find a driver for. I believe I installed all the drivers from the included disc with the motherboard and have tried having windows search for a driver online without finding anything. I don't seem to find anything related to the device on ASRock's website either under downloads available for the board.

Here is what appears under Hardware Ids for the device, anyone know where I can get a driver for it or fix this problem? Thanks in advance.

ACPI\INT33A0

I have the same thing on an ASRock z68 professional gen3 but only after my pc wakes from sleep. On a normal bootup there will be no "unknown devices" in device manager but if I put the computer to sleep, once I wake it up I get a little popup on my taskbar saying "your device is ready to use" (or something like that) and then sure enough in device manager I now have a unknown device.

The description on mine is similar:

ACPI\NTN0530 Location: on Intel(R) Z68 Express Chipset Family LPC Interface Controller - 1C44
*NTN0530

Once I re-boot my computer there are no longer any unknown devices in device manager so Im guessing im must be something thats having trouble waking from sleep (at least on my computer) Maybe someone with more knowledge has some insight?

Just install Intel Smart Connect software

ACPI\NTN0530

It seems to be Nuvoton w836x7hg integrated CIR, try if this can help you.
