IWD Bus Enumerator Driver

So I was busy trying to get my printer hooked up so I could print something and happened to notice there was a yellow sign with an exclamation mark on my computer in the hardware and devices window.  After looking at the properties I found there was an error with the IWD Bus Enumerator Driver.  I attempted to have Windows troubleshoot it twice to no avail.  I have been unable to figure out what this driver is exactly or what it does.  It seems pretty important since it is being flagged by the computer.  Also I am not sure if it was there before or after plugging in the printer.  Also attached to the troubleshooting report was something about a problem with some PnP devices.  Not sure if this is affiliated or not but was flagged with the other issue.  Any help with this is much appreciated, thanks.

I have a similar problem after upgrading to 8.1 on my Lenovo T430.  The IWD Bus Enumerator is listed in the device manager twice.  One is working properly, the other says Windows can't find the driver  "(Code 31)."  Posted a question on Lenovo's Thinkpad forum.  Waiting to hear back.  Still trying to find out exactly what a IWD Bus enumerator is.

UPDATE:  seems the problem with my computer was that the IWD Bus enumerator was in there twice.  I looked at the driver details and both had the up to date version.  So, I uninstalled the second one:  the one with the exclamation point, and all seems to be well.
