ABSTRACT:
In some embodiments, if a card in a card reader has not been accessed in a first specified amount of time, the card may be powered down. The card may be powered back up if an attempt is made to access the card. In some embodiments, if a memory card is in the memory card slot of the card reader, but has not been accessed in a second specified amount of time, the card reader may be electrically disconnected from the host controller if a sideband signal is available to signal the card reader when to electrically reconnect.
