I have same problem. I downloaded the latest webcam driver, installed it. Everything is fine, in the device manager the device are present. But when i try to load the webcam application from dell the device is not present or not installed appear.
Notice: if I try the YM webcam, the device work properly - that's mean the device driver is OK.
So the E6500 is a beautiful great notebook, with poor software.

It's a small button on the right. See http://support.dell.com/support/edocs/systems/late6500/en/sqrg/pdf/U084C0MR.pdf page 7 and 8
