To select a configuration for a USB device, the client driver for the device must choose at least one of the supported configurations and specify the alternate settings of each interface to use.

The USB bus driver selects each interface in the specified configuration and sets up a communication channel, or pipe , to each endpoint within the interface. After the request completes, the client driver receives a handle for the selected configuration, and pipe handles for the endpoints that are defined in the active alternate setting for each interface. Get the number of interfaces in the configuration. The number of elements in the array must be one more than the number of interfaces.

Initialize the array by calling RtlZeroMemory. Obtain an interface descriptor for each interface or its alternate setting in the configuration.
