WPD multi-transport sample driver
The WpdMultiTransportDriver sample demonstrates how you could extend the WpdHelloWorldDriver for a device that supports multiple transports. A transport is a protocol over which a portable device communicates with a computer. Example transports include Internet Protocol (IP), Bluetooth, and USB.
A number of portable devices now support multiple transports. For example, a number of cell phones support both Bluetooth and USB. Windows supports a multitransport driver model that ensures that only one node appears for each device.
For a complete description of this sample and its underlying code and functionality, refer to the WPD MultiTransport Driver description in the Windows Driver Kit documentation.
