Cant find Webcam driver for Dell inspiron15

Hello,

I bought a Dell inspiron 1564 just a few days back..
I did not get it with the OS and hence got no disks with that.
I have installed most of the drivers manually except the Integrated 1.3MP Webcam driver!
Windows 7 has some inbuilt driver support. But it is not helping in getting it to work.
So i needed to know from where i can get this driver? I couldn't find it in the internet.. Not even the dell support site :(
So is there any alternate driver or any other method to make it work..
Any kind of suggestion would be appreciated.. :)

Cheers
