Final answer:
The claim that VEXnet joystick firmware needs to be downloaded every time it is used is false. Firmware updates are only necessary when a new version is released, which does not happen every time the joystick is used. Always check for updates periodically or when performance issues arise.
Step-by-step explanation:
The statement that the VEXnet joystick firmware should be downloaded every time you use it is false. Firmware, which is the permanent software programmed into the read-only memory of the joystick, only needs to be updated when the manufacturer releases a new version to fix bugs or add new features. Regularly downloading the firmware every single time the joystick is used would be unnecessary and time-consuming. Generally, you should check for firmware updates periodically or when you encounter issues with the joystick's performance. If an update is available, then you can download and install it to ensure your joystick is functioning properly.
