Error while opening video device /dev/video0

I'm not familiar with the use of strace.  It turns out a huge stream 
of info and quickly fills the buffer(?).  I tried sending it to a 
text file - the file was written, but 0 bytes long.  I can copy and 
paste into a text file, but you will not see the early part of the 
report.  What now?
