What resolution and framerate are you capturing at?
640 * 480 * 30 fps * 2 bytes per pixel * 2 cameras is
37 megabytes per second.  That's probably over the practical limit
for high-speed USB.

The camera's chipset supports JPEG compression, but there's no
documentation on these parts and I never quite managed to get that
to work right.
