Odd. The Internet says it works.
If you already (manually) installed a driver for the cam then uninstall it.
Disconnect the camera and turn it off.
Reboot the PC.
Once rebooted completely make sure you have internet connection.
Connect the 350D.
Turn on the camera.
Now the driver search should begin and install automatically.
