Can you look at the kernel log (dmesg) and report messages printed by the uvcvideo driver ? > I also tried re-install original workable Linux, and make v4l again. > Then copy the newly build uvcvideo.ko to > /lib/modules/2.6.33.xx/kernel/drivers/media/video/uvc/ > module still can be found from lsmod, while gstreamer-properties still > can't find CNF7129 device. That's to be expected, as the new v4l-dvb build you installed replaced the core v4l modules (such as videodev.ko), and the new version isn't compatible with the uvcvideo driver that came with your kernel. > Does it mean I must do some code modification for 04f2:b071 device > before I build v4l driver? In theory, no. -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
