Recently I have Updated my Laptop from Windows 8 to Windows 8.1 single language pack.
Once Installation is completed, I faced problem in starting Dolby Audio driver, I have installed the latest driver and it got resolved.
Next came the problem in Bluetooth device in accepting files from my mobile, then done the same. Installed latest driver and it too got resolved. But still i am facing the message "Unknown device" in Lenovo Support Center in Device Manager.
I have checked in Device Manager. But no device is indicated in yellow color.
Please let me know, how to identify which device is causing this problem and how to rectify this.
My Laptop details:
Model : G580
Product ID : 20150
Let me know if you want more details.

I have tried it. But i am not able to get any info on right clicking on it.
Also there is no indication in actual Device Manager.

As I have already mentioned, I didn't find any device which is indicated as Unknown in Device Management.
I have shared the Images for your better understanding. It is only displayed in Lenovo Support Center alone.
