Generally those devices show up when the chipset drivers have not been installed. I would strongly suggest that you download and install those as found here. You can also go to settings in Windows and click on updates which may also find the required drivers.
So I just did a fresh reinstall of windows on my Alienware 15r4. I ran the automatic driver and software install from the support website . As well as support assist application from the PC after . It says everything is up to date and installed but I still get these errors from my device manager. I'll attach a image . Anyone have any idea how to resolve them . I already tried updating the driver directly from the device manager  [IMAGE]  
Need help fixing issue in device manager
