In 8.04 this "041e:4061 Creative Technology, Ltd Webcam" worked when I installed and compiled the driver: http://www.rastageeks.org/downloads/ov51x-jpeg/ov51x-jpeg-1.5.8.tar.gz.  It does not work any longer.  The LED lights up on the camera but no usable video comes out.

With kernel 2.6.27,  when I plug in the "041e:4061 Creative Technology, Ltd Webcam", the modules gspca_main and gspca_ov519 are loaded, and should not be.  This webcam is reported to work with drivers from: http://www.rastageeks.org/downloads/ov51x-jpeg/ov51x-jpeg-1.5.9.tar.gz.  When I rename gspca_ov519.ko to gspca_ov519.ko.old and build and install the new ov51x-jpeg-1.5.9.tar.gz drivers, the gspca driver no longer installs and the ov51x-jpeg driver does install but the camera still is broken.

Universe contains an older version of this driver ov51x-jpeg-1.5.8.tar.gz from Debian, this version will not compile against a 2.6.27 kernel and needs to be updated.  Also the gspca_main and gspca_ov519 modules need to be blocked from loading from either of the 041e:4061 or the 041e:4068 webcams as they do not provide the jpeg decompression.

The current ov51x-jpeg-1.5.8.tar.gz driver in Universe should be removed or updated to the latest driver as it has no chance of ever working with a 2.6.27 kernel.  The ov51x-jpeg-1.5.8.tar.gz compiled against the 2.6.26 kernel that was being used for Intrepid but with the change to 2.6.27 that breaks and requiresov51x-jpeg-1.5.9.tar.gz
