Most of Sony Vaio laptops come equipped with the motion eye webcam, which unfortunately doesn't get detected on linux automatically. On my machine, lsusb command lists the camera as
Bus 001 Device 003: ID 05ca:1839 Ricoh Co., Ltd . But no modules are loaded by the kernel and no video devices are created in /dev. Installing the driver is easy, but some configuration is required.
1. Make sure the kernel development headers are installed
sudo yum install kernel-devel
2. The drivers are hosted at http://wiki.mediati.org/R5u870. Download the latest source from svn.
svn co http://svn.mediati.org/svn/r5u870/trunk r5u870
3. make and install
sudo make install
4. Copy the firmware files to /lib/firmware
sudo cp r5u870*.fw /lib/firmware
5. Load the module
sudo modprobe r5u870
Now you need to blacklist the default uvcvideo module from loading(Source : http://ubuntuforums.org/showthread.php?t=706530).
6. Create a new file in /etc/modprobe.d
sudo touch /etc/modprobe.d/uvcvideo-blacklist
7. Add the following line to the newly created file and save
Restart the machine for changes to take effect. Then run the following command to test whether everything is working correctly. (Source : http://ubuntuforums.org/showthread.php?t=706530).
gst-launch-0.10 v4l2src ! ffmpegcolorspace ! ximagesink
If you can see yourself , the driver has installed correctly. However, to get it working with cheese and some other utilities, you need to create the haldaemon fdi file as described in http://ubuntuforums.org/showthread.php?t=706530. Download the attached file from the above link and then run the following commands.
sudo cp 10-r5u870-webcam.fdi.txt /usr/share/hal/fdi/information/20thirdparty/10-r5u870-webcam.fdi
sudo service haldaemon restart
That's it !. Enjoy !!
