I have successfully installed 3.04 and have downloaded several programs to my students cortex via the USB direct connect. My game controller responds to my code driving the robot as intended. Now I am trying to download the same program using the USB to serial connection on the controller to the cortex. I keep getting an error, "Failed to verify that a connection is available" and then the message box gives me several ideas all of which I think I've done. Any help???

Have you downloaded the driver for the USB to Serial Programming Cable? You can find it here: http://www.robotc.net/download/cortex/

Also we have tutorials in the Setup > System Configuration section of the VEX Cortex Video Trainer that should help you verify your settings: http://www.education.rec.ri.cmu.edu/pro ... index.html

yep. reloaded all software and same result. Even tried another program using the direct USB connection to the robot and everything programmed fine. When I tried to do the same using the game controller connection the same result as before. "COM PORT, com9 cannot communicate with game controller"

All set..... I got it. Thanks.
