Hello,
I'm using a Packard Bell MX36 laptop with an m5602 Webcam on Mandriva 2008
Spring and a 2.6.24.4 kernel.
I tryed the last m5602-ov9650-2 ( 134 ) and my webcam is well recognized
dmseg :
Linux video capture interface: v2.00

BisonCam on /dev/video0 opened
Before this version, the sensor was not recognized and I had to use force=1
when I loaded the module.
The Bayer mode just show me a black picture and the fps is 0 or 1.
The problem is that LiveCam crash when I try the RGB mode and dmesg send me
