X1 Carbon iwd bus enumerator error after windows 8.1 upgrade

2013-10-18, 6:40 AM

Upgraded my X1 Carbon (touch) to Windows 8.1 today.

 

The LSC reports that iwd bus enumerator is not working. Going to the device manager verifies this. But, there are two entries in the device manager for the iwd bus enumerator: the first listed is working properly, the second listed is not working properly. It has this message:

 

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

Object Name already exists.

 

Looking for a remedy.

I resolved my issue by going to device manager selected View then View Hidden Devices.

 

Expand System Devices

 

Found two IWD BUS devices and one had the yellow triangle. I uninstalled that item and restarted my Carbon X1 and the error was gone. The original working IWD BUS remains active.

Uninstalling the second, non-functioning device driver seems to work for me, too.

I too have uninstalled the second one.


Be good to know what they do and if uninstalling the second one might be not a good idea.

Same problem with the X1 Carbon.  I deleted the 2nd one but now I can't find the 1st one.  Any suggestions?

 

What does the IWD Bus Enumerator actually do?

 

I'm having a problem extending my display to a 2nd monitor.  Is it related to that?
