My VPCSB Vaio shows the camera as 'USB 2.0 Camera' in Device Manager and shows the driver as USBVIDEO.SYS which is a Windows 7 generic driver and is part of the Windows 7 installation..  My built -in webcam is not capable of zoom or pan but it is an older model than yours.

I think your webcam is working as it should.  Where did you get the information that it can zoom and pan?
