Here's what I get before the driver registers the camera: # ls -al /sys/class/video4linux/ total 0 drwxr-xr-x 2 root root 0 2009-01-06 17:41 . drwxr-xr-x 37 root root 0 2009-01-06 15:08 .. And here's what I get after: # ls -al /sys/class/video4linux/ total 0 drwxr-xr-x 2 root root 0 2009-01-06 17:39 . drwxr-xr-x 37 root root 0 2009-01-06 15:08 .. lrwxrwxrwx 1 root root 0 2009-01-06 17:41 video0 -> ../../devices/pci0000:00/0000:00:1e.0/0000:02:09.0/0000:03:00.2/usb5/5-1/5-1:1.0/video4linux/video0 > luvcview is giving me error: > "ERROR opening V4L interface : No such file or directory " > Is it because the cam is not registered as /dev/videoX > > Will it work fine if I use latest uvcdriver code?

That won't help you for video streaming :-) Best regards, Laurent Pinchart _______________________________________________ Linux-uvc-devel mailing list [email protected] https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
