I have a acer aspire 4720 with a built in CrystalEye web cam ( Manufacturer is Suyin). I am running fedora8 on it.I am unable to install and use my webcam in linux.I find my camera when I do a lsusb it shows up correctly

I have installed the Linux UVC kernel driver from the berliOS site ( The webcam is listed as being supported by the driver) svn checkout svn://svn.berlios.de/linux-uvc/linux-uvc/trunk
However, the lsmod command doesnot show any drivers uvcvideo.ko installed . I am quite confused.
I have downloaded the luvcview repository and successfully compiled and installed luvcview.When I run the following command I get the result :- [root@localhost dev]# luvcview -y yuv
Video driver: x11
A window manager is available
Device path: /dev/video0
ERROR opening V4L interface: No such device or address
I have installed v4l2 and I have also got the SDL libraries in place.
Did you load the driver for the webcam ? modprobe uvcvideo
I have an Acer netbook wiith the Crystal eye webcam, it's from a different manufacturer than yours, although apparently it uses the same driver, which in my case was already included with the kernel

This is on Debian Lenny new install..
Hopefully something here might help.
cheese was loaded on this machine to capture video and puctures. It was all apparenlty detected during install I didn't have to do anything to get it working. I actually ran Cheese asking myself "what is this program for? " and next thing I know I was staring at myself.. That was pretty scarry.
when you modprobe the driver does it give you any errors ?
does it show as listed then ?
thanks for your response...I too figured that out today. My uvcvideo driver was missing.
So here is what I did for that :-
I went to the berliOS site and downloaded the svn repository for the uvcview driver.
I did a make , make install for it
I restarted the machine
When I did a dmesg | grep Crystal it showed my webcam correctly and then I checked out the driver too using lsmod | grep uvcview and it too showed up nicely.
Next I start up the luvcview utility and it showed my happy face
By the way what utility do you use to capture still images and video from your cam ? I could use some help on that !
