Plugable and Windows 8.1

I’ve been using the Plugable USB 3.0 docking station with my Surface Pro and it worked great until I upgraded to the Windows 8.1 Preview. Now, I don’t get anything on the second monitor and the Surface keeps trying to reinstall the DisplayPort driver. It tells me to reboot, and after I do, it tries to install the driver again and asks me to reboot. It repeats the process over and over.

Are you aware of any issues?


same happens to me!

very frustrating too. I need both monitors and now I’m unable to get both to work. has to be an issue.

The preview of Windows 8.1 just came out yesterday, and it appears to break compatibility with many existing drivers.

When you upgrade to 8.1, drivers are not migrated from 8.0, rather they appear to be re-enumerated and re-installed.

The most widespread change is new driver signing requirements which may cause many 3rd party drivers to need an update. Also specific to USB graphics is Windows 8.1 introduces a new WDDM 1.3 graphics model, which requires some additional updates.

All that said, DisplayLink appears to be doing a good job of staying ahead of all these changes (they’ve been working with earlier NDA builds, in partnership with Microsoft), and have released their preview driver with support for Windows 8.1 on the same day.

DisplayLink’s 7.4 preview driver with Windows 8.1 support is available here:…

We installed Windows 8.1 when it came out yesterday, and the new DisplayLink driver, and while I’m sure there’s issues there somewhere, all of our quick tests showed good results in a production environment.

So for anyone updating to Windows 8.1, please install the DisplayLink 7.4 Preview driver. You can even do this before the upgrade – the 7.4 preview works also on earlier versions of Windows, and when 8.1 does a re-enumeration it will find the driver if you’ve already converted over. A reboot may be required to get things to settle.

Hope that helps – and if you do find any issues, let us know. Or post on DisplayLink’s forum (the link above) to get the feedback directly to them.

Thanks again for posting to ask!

Ethernet is not working on my USB 3.0 Docking Station after the Windows 8.1 update. It’s listed in the device manager but has the yellow exclamation mark on the icon.

Also I have several other USB unknown devices listed with the yellow exclamation mark icon as well. External keyboard and mouse through the USB dock are working fine. Also only one of my external monitors is displaying anything, my third is not.

FYI, latest driver is installed.

Any help would be appreciated, Sam.

Some more info -

The Plugable UD-3000 is listed under USB display adapters along with 3 other DisplayLink Display Adapter listings with different numerations on them.

I have restarted several times and even uninstalled everything and re-installed the new driver.


I’m not seeing that same issue, but I’m running the Windows 8.1 Preview. I’m currently using Ethernet through the dock on my Surface Pro. I did have to reinstall the proper drivers after upgrading to the Preview, but then everything worked fine.


This is what I get on the DisplayLink Network Adpater NCM porperties window -

"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."


Hi Sam,

The DisplayLink Network Adapter problem you are experiencing is likely due to Windows selecting the wrong Ethernet driver after updating from Windows 8 to Windows 8.1

The way to solve this issue is to remove the DisplayLink Network Adapter NCM driver and re-install the drivers located at C:\Program Files\DisplayLink Core Software\CdcNcmDriver\Ndis6.2.Hck81

Here is the step-wise way to do this.

  1. Locate the Device Manager

  2. Locate the DisplayLink Network Adapter in the Device Manager and select the device properties

  3. Select the Driver tab and Uninstall the driver, make sure to have the “Delete the driver software for this device.” checked. !](](

  4. Re-install the appropriate driver. Opt to browse your computer for driver software, the driver will be located at C:\Program Files\DisplayLink Core Software\CdcNcmDriver\Ndis6.2.Hck81
