Stephen, Thanks, this was the problem. There is always more to learn. :-) I had my ov511 module built into the kernel, so I had to recompile that to be able to use it as a module, but things worked great as soon as I did so. For others with the same problem, add the following to /etc/modules.conf alias char-major-166 ov511 options ov511 cams=2 I am not yet sure if I will be able to use this for playing around with stereo vision due to the way the two cameras refresh. One then the other, but I'll play around and see if I get their refreshes to be in synch with each other. Adding a second USB controller card may help out with the speed / refresh problems. Unfortunately, the machine I am currently using is a bit old and only has a single USB bus/controller.
