What does it mean when the lights on the hub are flashing?

When the lights on the hub are flashing, it indicates that the hub will deactivate in 3 seconds. This is a visual status update that lets users know the hub is going through a shutdown process. Flashing lights serve as a warning signal, thus ensuring that users are aware of the impending deactivation, allowing them to take necessary actions, such as saving data, if applicable.

In the context of the other options, while a hub can prepare for a match or be in use, these states would typically not be indicated by flashing lights. Instead, steady or different-colored lights would likely represent those statuses. Similarly, a connectivity issue would be better indicated by a different light pattern or color, rather than simply flashing. Therefore, the flashing lights distinctly signal that the hub is entering the deactivate sequence.
