Here is a snippet of my config: # # Multimedia core support # CONFIG_MEDIA_CONTROLLER=y CONFIG_VIDEO_DEV=y CONFIG_VIDEO_V4L2_COMMON=y CONFIG_VIDEO_V4L2_SUBDEV_API=y CONFIG_DVB_CORE=m CONFIG_VIDEO_MEDIA=m > And does your system run udev, or have you created the device nodes manually ? It runs udev-173... I didn't create the nodes manually. I also have the /dev/v4l-subdev0 to 7 entries, as expected. Anything else I should check?
