OK.  I have a C program using opencv that opens a jpeg file , inverts it 
and displays it.  I had tried to modify it to grab a frame from the 
camera, instead of a file, but it had not worked, hence, my last post.  
Today I tried again and now it seems to be working just fine.  I didn't 
do anything different, but it is working now, so I am happy.

Thanks to everyone who helped me get the correct driver compiled and loaded.
