Has anyone had problems opening 2 USB camera streams at the same time if they are both the same brand and model? [closed]

I am trying to play around with a stereo camera rig I built. Both cameras are exactly the same, 2.0MP ELP brand. It uses the USB Video Class (UVC) 1.1 driver. Both cameras are tested and working. I can open them individually in a simple opencv c++ program. The stereo program i wrote works with one ELP camera and my Logitech webcam. (and that's with all three USB cameras connected to the pc.)

Are they connected to the same (internal) USB-HUB. What happens if you want to open them (error message)

They are connected to the same external hub, in fact all three are. No error messages.

VideoCapture rightEye;
rightEye.open(i);

I iterate through 0-9 in a for loop.

Is there a way to pick the camera by a means other than some integer value that windows assigned?

The brand of the camera is irrelevant for the bus. It all depends on in which USB-socket you plug your device.
