    Yesterday I wanted to connect my Lumia 820 with my Win8 laptop for the first time, that time it worked fine.. It was showing as Windows Phone - Portable device

    But today when I again tried to connect it, Windows is giving me a error message like- Usb not recognised.. Even Device manager not detecting it at all.. Only shows as Unknown Device in other section, just for few seconds..

    Tried in my friend's Win7 desktop computer, still same error showing..
    I've searched a lot in Bing. Didn't find any appropriate solution..
    I've tried processes like [link]http://support.microsoft.com/kb/2749484?wa=wsignin1.0[/link]


    Please give me the solution.. What can I do now?

    You tied everything in the link you posted? If so you may have bad hardware as those steps have always resolved that issue for me in the past. The first thing I always do is a soft reset of the phone by holding the power button and the volume down button until the phone vibrates and reboots.
