This is quite outdated. You can find a newer version in the quickcamteam.net 
SVN repository (http://svn.quickcamteam.net/svn/luvcview/) where luvcview 
sources are now maintained.

I'm a bit puzzled by this error message. I can't see it in any source file 
I've checked (luvcview, libv4l, Linux kernel, ...).

The unsupported ioctl number corresponds to VIDIOC_QUERYCAP which the uvcvideo 
driver supports.

Could you please set the driver's trace parameter to 255 (echo 255 
> /sys/modules/uvcvideo/parameters/trace), rerun luvcview and check the 
kernel log for any error message ?
