    I have a HP630 notebook with windows 7 Home Basic OS. I upgraded it to windows 7 premium and downloaded all the drivers. These driveres were installed properly. My laptop was working fine until recently. Now the webcam is not working. Whenever, I open Skype, my webcam does not turn on and an error message is shown ' Webcam is Off. If you have integrated webcam, turn it ON'. Secondly, I noticed that device manager shows " unknown device" in USB devices. When I checked for it error code it indicates " windows has stopped this device (error code 43). I feel that stopping of webcam and unknown device error are two issues which are related to the webcam malfunctioning. I remember that webcam was working OK earlier. My question is how to solve this problem.

    There should have been no drivers to be installed. If you already had them in Home Basic, why did you change them? You should have saved the ones you had before upgrading, just in case.

    Did you try uninstalling it and reinstalling it in device manager?

    Also, did you try to look in Reliability Monitor to see if it had anything to say? Access Reliability Monitor from the search bar by typing Reliabiliy Monitor.

    I did install the cyber cam driver software, still the problem persists. Also tried to unstall and delete unknown device which also does not work. It seems that installing OS again is one of the options. Can any one suggest otherwise?

    Is the webcam connected with usb or it's build-in ? if it's build-in it's not related to unknown device" in USB devices", is there something like "Imaging devices" (or something like that) category in your device manager ? Usually, build-in webcams will list under this category.

    You are right. When I formatted the hard disk and reloaded Windows 7 home premium, my webcam got detected and it was shown in imaging devices. It was working also fine through you cam software. When I loaded SKYPE software, the problem reoccured. Now the webcam is gone and there is device error in USB devices with errorcode 43. I suspect that SKYPE is not suitable for 64 bit machine or it is not compatible to the web cam supplied by HP. May be some one will have answer. Finally, I have decided to forget SKYPE and use PC with webcam. Do you recommend any other software to keep it working?

    The problem was in the hardware. When I contacted HP they replaced the panel which includes webcam and built in microphone. The problem was solved. Thanks to all who helped me.
