When trying to connect our robot to the computer, we get the following error message:
Can not communicate with VEX Cortex slave CPU. "Master CPU communication is working."

We are using a USB to USB cable from the Computer to the Cortex. We are running RobotC v.4.26. We just upgraded the firmware with the VEXnet Upgrade Utility v4.1.5 (it says "VEXnet is up to date no action required")

Is the slave CPU the joystick controller? What can we do to fix this problem?

Please help.

I did not find the right solution from the internet.
