I've never seen similar errors on my systems when using luvcview. This one  
doesn't even look like a uvcvideo or V4L2 problem on the input side but it  
looks like SDL is having problems initializing the output window.

That still wouldn't explain the failure with headless programs, though.

So can you execute
   echo 64 > /sys/module/uvcvideo/parameters/trace
to increase uvcvideo's debug output level and post the syslog output you  
get after plugging in your camera and trying to run the capture programs?

Cheers,
Martin
