How to calculate potential bandwidth on USB when using structure light sensors?

I have a structured light sensor that is running a ROS driver. I would like to calculate how much data I am pumping through my USB cables to see if I am running into any bandwidth issues. Right now I would like to subscribe to the pointcloud (sensor_msgs::Pointcloud2) as well as the image and depth image (sensor_msgs::Image) that are of a resolution 640 x 480. How can I determine if there is sufficient bandwidth in my USB cable to subscribe to all three at once?
