Hi viswas,

Thank you for the information. I suggest that you unplug any USB connections and refresh your laptop. Then try using your webcam. I believe the issue to be with the USB connection that is giving you the error and not your webcam. Here is a document for how to Refresh Your PC to Resolve Problems (Windows 😎.

If you are still having an issue with the webcam then one of the documents in the previous post should help now. Any Windows 8 document steps will be the same for Windows 8.1.

I am also including this document for How To Fix Code 43 Errors that will help determine which USB product is causing the error to appear.

The error actually was due to something else.
Disable the driver and shutdown the system now remove the battery set it aside for sometime now restart and enable the driver it works fine
