I have already installed gspca. When I try to test the webcam using
gstreamer-properties I get the following error :

gstreamer-properties-Message: Error running pipeline 'Video for Linux
2 (v4l2)': Error starting streaming capture from device '/dev/video0'.
[v4l2src_calls.c(1392): gst_v4l2src_capture_start ():
/pipeline0/v4l2src3:
system error: Protocol error]

Also cheese gives this error :

(cheese:9072): GStreamer-CRITICAL **: gst_element_set_state: assertion
`GST_IS_ELEMENT (element)' failed

(cheese:9072): GStreamer-CRITICAL **: gst_object_unref: assertion

(cheese:9072): GStreamer-CRITICAL **: gst_object_unref: assertion

I guess uvcvideo is the driver for my webcam. But it won't work.

I tries to reload the driver as modprobe uvcvideo but still it doesn't work.
