This is what we use and it works great

works great.....make sure you have your ports and everything configured....more information about that can be found on
http://kevin.org/frc/
to set up.....check what port you are using by going to your control panel, system, hardware, device manager, ports (com and lpt), find where your cord is hooked up and then when you start the program, put the number of the port you are using.....
it should say searching for camera....and then give you the camera name and a version number
Good luck and feel free to email me if you are still having problems....
