You can checkout the latest v4l-dvb source from mercurial (or download a snapshot), and run make SRCDIR=/path/to/your/kernel/2.6.33/source/tree Make sure your kernel source tree has been configured (you might need to compile it as well, not sure about that). > [ 78.446109] uvcvideo: Found UVC 1.00 device CNF7129 (04f2:b071) > [ 78.462540] ------------[ cut here ]------------ > [ 78.462569] WARNING: at drivers/media/video/v4l2-dev.c:420 > __video_register_device+0x44/0x3d7() [snip] I'm pretty sure this is a mismatch between the uvcvideo and videodev kernel modules. Please reinstall the whole v4l-dvb subsystem, either from your distribution packages or from the v4l-dvb repository. Make sure both the uvcvideo driver and the v4l-dvb core come from the same source. -- 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
