Can any one help?

I have to USB web cam and I'm trying to access them at the same time to creat a cheap stero vision system for me to play with.

My problem is when I write my own code using the Active X control or use the sample code base on two fire wire cams the program locks when you try are start both cams. I think it could be related to band width so I set the image at I420 (160x120) for both which should be well inside the bandwidth for USB (no effect).

any ideas?

It seems, the bandwidth is too low. A easy solution can be to use a second USB board in you computer.

The programm sample does not lock up. After a time out time the message "USB Controller bandwidth exceeded" is displayed.
