Cant use Crystal Eye webcam on my Acer Laptop with Fedora 9

[Rohan Kulkarni]

Hello,
        I have installed Fedora 9 on my Acer Aspire 4720 laptop. It
has a Crystal Eye Webcam. But with Fedora 9 I cant use it. It is
working fine with Windows XP. It is detected properly but doesn't
work. I installed cheese and skype but the webcam doesn't work in
either of them.
gstreamer-properties shows the default video input plugin as v4l2 and
device as Acer CrystalEye webcam but the test for the webcam fails.
What should I do to make the webcam work?

Thank you
