Web Cam in Dell SP2309W

The web cam in my SP2309W has stopped working. I have the inboard usb cable connected from my Studio XPS 435MT. I can plug a usb mouse or card reader in the monitor and they will work, so the cable is ok.
I have downloaded the driver from Dell, the latest Dell web cam software and the latest Many Cam software.
When I open the Dell web cam soft, I get a message saying plug in the web cam. I also have an unknown device showing up in USB controllers in the device manager.
Anyone have anything else that I can try?
