Toshiba Satellite A200 runniing Windows Vista - Built in Webcam stopped working

Although this had nothing to do with with Microsoft Anytime I was getting the following message:
When you select Start Camera in the Camera Assistant software you may see this error message: "Please turn on the Camera".

After wasting half an hour trying to reinstall the driver, down load the orignal software etc, I stumbled across the soltuion on the Toshiba site:

Firstly
Re-install the driver for the webcam.

Then Follow these steps to re-install the driver for the webcam.
You will need to be logged in as an Administrator or have an Administrator password ready.

1. Click the Windows Start button.
2. Click Control Panel, System and Maintenance and then Device Manager.
3. Right-click on Chicony USB 2.0 Camera and select Update Driver Software. A yellow exclamation point indicates that the camera is recognized by Windows but is not working properly, probably because of problem with the device driver
4. Select Browse my computer for the driver software.
5. Select Let me pick from a list of device drivers on my computer.
6. Select USB Video Device from the list, and click Next.
7. If the message “Windows encountered a problem installing the driver software for your device” appears, click Close.
8. Restart Windows.

The webcam should now work properly.
