Yes it's possible but the usb bandwidth is shared between your two cameras.
Pwc camera can only use the Usb1.1 so it's limit to ~800Kbytes/s. When
displaying with two camera (or more), so you can try to:
- lower resolution
- enable compression (use a greater level)
- connect each camera on a different USB host controller

Another solution: Lower the framerate. The Logitech Quickcam Pro 4000
supports framerates that are multiple of 5. (I don't know about other
models)
