What action should be taken if the VEX Cortex is not recognized by the computer?

When the VEX Cortex is not recognized by the computer, checking the connection and attempting to reconnect is the most logical first step. This action addresses the fundamental requirement of ensuring a proper physical link between the Cortex and the computer. Loose or faulty cables often cause communication issues, so verifying that the USB cable is securely connected to both the Cortex and the computer can resolve recognition problems.

This approach allows for immediate troubleshooting without needing to take further measures that might involve more time or complexity, such as restarting the computer or reinstalling software. While these actions could potentially resolve the issue, starting with a simple check of the physical connection is the most effective and straightforward method. If the connection is confirmed to be secure and the problem persists, other actions might then be warranted, but reconnection should always be the first step to take.
