METHOD FOR MANAGING THE PLUG-IN OR REMOVAL OF A MEMORY CARD INTO OR FROM A CARD READER AND APPARATUS FOR USE IN SAID METHOD

摘要

The proposal relates to the handling of the insertion and removal of a memory card into a memory card reader (11) that is itself connected to a central device (10). The insertion and removal of a memory card from a memory card reader (11) is not reported to the central device (10) via the bus connection (13), which can be a USB bus connection. This causes a problem that the user and the central device (10), e.g. a DVD player can be confused. This will also if the memory card is removed from the card reader (11). The content or file directory for this card however, is shown on the UI of the player despite of that the card has been removed. To overcome this problem it is proposed to implement a polling method in the central device (10). At regular intervals, e. g. 100 ms a player (10) will send control commands for reading the status of the various slots (12) of the memory card reader (11).
