Abstract
A filter driver (125) can communicate with the USB stack and controller and with the CardBay, CardBus, and flashmedia stack and controller. This can allow the use of a CardBay card in a CardBus socket in a manner that is transparent to the user.
Claims20
A data processing apparatus, comprising:
- a connector for receiving a media card;
- a first communication port coupled to said connector and operable when a media card is in said connector for communicating with the media card according to a first communication interface;
- a second communication port coupled to said connector and operable when a media card is in said connector for communicating with the media card according to a second communication interface that differs from said first communication interface;
- a data processor coupled to said first and second communication ports for communication therewith, said data processor for implementing first and second software drivers which are operatively associated with said first and second communication ports, respectively;
- said first software driver cooperable with said first communication port when a media card is in said connector for determining whether the media card communicates according to said second communication interface;
- and
- said data processor for implementing a third software driver that interfaces between said first and second software drivers, said third software driver for receiving from said first software driver an indication that a media card in said connector communicates according to said second communication interface, said third software driver responsive to said indication for directing said second software driver to enable said second communication port.
