Problems with webcam

driversskypetroubleshootingwebcamwindows 7

My friend is using Windows 8.1, and he has a webcam. He says it is working very well even without installing drivers.

Webcam is A4tech – PK-331F.

I asked for this webcam for use.

I plugged in the webcam, and Windows detected it and installed drivers automatically. Then I opened Skype to check the webcam. I got a message from Skype that said, "Your webcam has microphone." When I clicked over it, it directed me to sound settings where it showed that the webcam microphone was working. I went to video settings, but the webcam wasn't listed there.

As you can see in the image, the webcam is not listed. It is listed in Device Manager but isn't listed in Skype.

I am using Windows 7 Professional 64-bit. Any idea why this is happening?

UPDATE
Here is the hardware lds from webcam installed drivers.
