Default Windows 8.1 DisplayLink Network Adapter Error with 7.4 M2

Hello,
I have just upgraded to windows 8.1 and installed DisplayLink 7.4 M2 software on my Dell XPS 14 laptop connected to a Targus high speed 3.0 USB dock. After the installation of the DisplayLink software, most everything started working as expected, but my NIC does not seem to work. When looking at the DisplayLink Network Adapter NCM properties, I get the following error:

This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)

An object ID was not found in the file.


I have attempted to completely uninstall the DisplayLink software and even went so far as to use the cleanup utility to ensure everything was removed from the system. I then rebooted, reinstalled and came up with the same error.

I have also attempted to manually update the driver in the system device manager, but that indicated the driver was already up to date.

I've attached the logs from the Diagnostic file gathering tool.
DisplayLink Support Files.zip

Please let me know if you need anything else from me.

Hi,

Can you try these steps?

Right click on device in device manager
Select Driver
Select Update Driver
Select Browse my computer for driver software
Select Browse
Enter C:\Program Files\DisplayLink Core Software\
Check Include subfolders
Select Next

Let me know how you get on.

Thanks,
James

Hi James,
Thanks for your response. I followed the instructions and was told that the driver was already at the latest version.

After I attempted that, I uninstalled the DisplayLink Network Adapter NCM NIC. After that, I scanned for hardware changes. When I did that, I was able to connect and use the DisplayLink Network Adapter NCM NIC, but my monitors stopped working. I rebooted the server and after the reboot, the monitors started working again and the DisplayLink Network Adapter NCM NIC was displaying the original error again and unusable.

Thanks.

Hi,

Thanks for the information.

I've raised this internally for further investigation.

Thanks,
James

Have you tried power cycling the dock to see if that recovers it?

Similar problem with a Dell U2713HM monitor. Log files attached, hopefully they help as it's a pain to have to plug the network cable into the laptop directly.

Are you seeing the same error code in device manager and rebooting or power cycling the dock doesn't solve it? Or updating the driver and pointing it to the driver in:

C:\Program Files\DisplayLink Core Software\CdcNcmDriver\Ndis6.2.Hck81

Which is for Windows 8.1. I wonder if it is loading a driver from a different directory.

Thanks!!

It worked for my Lenovo USB 3.0 Port replicator, but I had to remove it first from the device manager, reboot, then the device reloaded with older driver. Then I followed your procedure!

Don't think so. I tried what you suggested and it tells me I have the latest driver loaded. I'm using an HP 3005pr. The specific error message is:

This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)

An I/O operation initiated by the Registry failed unrecoverably. The Registry could not read in, or write out, or flush, one of the files that contain the system's image of the Registry.
