I just tried this kernel with my board.  The media control infrastructure
comes up and all of the devices are created, but I can't access them.

 From the bootup log:
   Linux media interface: v0.10
   Linux video capture interface: v2.00

When I try to access the devices:
   root@cobra3530p73:~# media-ctl -p
   Opening media device /dev/media0
   media_open_debug: Can't open media device /dev/media0
   Failed to open /dev/media0

The devices look OK to me:
   root@cobra3530p73:~# ls -l /dev/v*  /dev/med*

Ideas?

Thanks
