Hi all, after three days of reading through forums and trying out different things, I finally decided to post a thread myself, as none of the posted solutions worked for me. My problem: My webcam suddenly frooze while using it with skype. That happened sometimes before alreday. Usually it works again after clsong the video connection and starting it again. This time after clsoing my video connection, the button for video calling disappeared and I got a message at the bottom right corner of my screen that I have a USB connection problem. At the same time, I was updating windows vista. Specifications: Asus X55sv notebook built-in 1.3 MP Chicony 2.0 USB webcam Vista Home SP2 Notes: - Can't find an imaging device in device manager any more. However, one USB port is unidentified. It says no drivers are uploaded for this product, but it also says that this device is wirking correctly (I'm not sure whether this has anything to do with the problem). - Several tries of installing different camera drivers always failed. - System restore to a point before I did the vista update failed. - However, when using programms like Driver Max to identify the hardware, a webcam is found, but no specifications are given. - I had this problem before when I bought the notebook ~2 years ago. But then, it could be fixed by installing the latest drivers. - The energy settings I'm using on my notebook do not allow USB ports to go to sleep mode in order to save energy. Any help (apart from reinstalling the OS and sending the notebook back to asus) is highly appreciated. Many thanks!
