Dear Maintainer,
* What led up to the situation?
Attempted to open access to a second device (camera)
* What exactly did you do (or not do) that was effective (or
ineffective)?
wrote the attached program which minimally opens the stream from the second
camera
* What was the outcome of this action?
The program reportes that although the first camera was accessible, identical
code opening a stream for a second camera was not successful
* What outcome did you expect instead?
Expected ioctl to return r==0, indicating successful system call
