An inserted card has been registered by the system and is ready for use.
If you specify a title, only the card with a title containing the specified characters will match this event context, thus allowing you to do different things depending on which card is inserted.
You can set the title of a card by creating a file in its base (root) directory called xxxxx.ttl (replace xxxxx with the desired title).
If you specify a Frequency and it's greater than 1, the event will only match if the card has been mounted a multiple of Frequency times since the last reboot. For example, a Frequency of 3 will match when the card has been mounted 3, 6, 9... times.
