ABSTRACT:
A memory card reader is disclosed that includes a memory card slot adapted to allow insertion and extraction of a memory card, a universal serial bus port, and a communication controller adapted for electrical communication with a memory card in the memory card slot and the universal serial bus port. The communication controller is responsive to a command message received in a command descriptor packet at the universal serial bus port to query the memory card in the memory card slot for information uniquely identifying the memory card. The communication controller is further adapted to generate an information descriptor packet including information uniquely identifying the memory card for provision at the universal serial bus port.
