\Driver\WUDFRd failed to load for the device ACPI\PNP0A0A\2&daba3ff&2

PJay_D · Feb 19, 2015

I have a strange error appearing in my system log each boot up:

The driver \Driver\WUDFRd failed to load for the device ACPI\PNP0A0A\2&daba3ff&2

This would appear to be some sort of driver error (possibly linked to power management) but I don't seem to be having any serious issues with my system and I have no devices in Device Manager showing an error.

I was wondering whether anyone could shed any light on what's going on?

I'm running an Intel 4790K i7 on an ASUS Z97-P motherboard; the OS is Windows 8.1 (upgraded from 8 via Windows Update).

check the bios and acpi driver also the utilities from asus for your motherboard they have some update since board came out http://www.asus.com/ca-fr/Motherboards/Z97PRO/HelpDesk_Download/

Thanks, but I've got the latest bios and all up to date drivers in place; is there a specific ACPI driver I should be looking for?

it might be the ASUS COM interface

Cheers, but I that installed too; at least it's showing as working in the device manager.

There's a fair amount on the internet relating to this error and ASUS boards, but I haven't found a fix that works yet. It may be fine to ignore it as I'm not having any major issues but it would be nice to sort it out.

I had thought of refreshing my Windows install, but having upgraded to 8.1 from 8 via Windows Update, my 8.1 installation won't refresh from my original Windows 8 DVD - so it would have to be a fresh install which feels a bit drastic (and still may not solve it).

I think asus com is a service and would not be shown in device manager. I would run control panel services and see if there is an "asus com" service that is disabled or not currently running
asus com = %ProgramFiles%\ASUS\AXSP\1.00.13\atkexComSvc.exe

Thanks again but the ASUS Com service is installed an running (along with several other ASUS services) although I haven't got the AI Suite installed. This was one of the suggestions I found on the internet.

I have seen it suggested that the failed load might be an early stage error and that the driver successfully loads later; but I'm not sure how I might check this out.

If you've installed the "Asus COM" service, and it has started without errors, Device Manager will show the device as "AMDA000". Do not make the mistake of assuming that "This device is working properly." means that the hardware is working. It does not. It only tells you that the driver initialized without errors.
