    All,

    I'm having problems with my webcam. All the drivers seems to be installed correctly it picks up that it should use uvcvideo driver and loads the appropriate kernel module. See dmesg output below:

    [user@localhost ~]$ dmesg | grep video
    Boot video device is 0000:00:02.0
    Linux video capture interface: v2.00
    uvcvideo: Found UVC 1.00 device Acer Crystal Eye webcam (064e:d101)
    usbcore: registered new interface driver uvcvideo
    .

    The problem is when I run anything to display th video (ucview (webcam app in fun) , skype, cheese) it fails to display the video.

    Cheese does give me the followoing output when run in the ternimal:

    ** Message: Probing the webcam, please ignore the following, not applicabable tries

    I've used v4l2-tool to probe the webcam device and all seems to be as it should all parameters are return appropriately (see screenshot below)
