UcmInitializeDevice function (ucmmanager.h)
Initializes the USB connector manager framework extension (UcmCx).
Syntax
NTSTATUS UcmInitializeDevice(
[in] WDFDEVICE WdfDevice,
[in] PUCM_MANAGER_CONFIG Config
);
Parameters
[in] WdfDevice
A handle to a framework device object that the client driver received in the previous call to WdfDeviceCreate.
[in] Config
A pointer to a caller-supplied UCM_MANAGER_CONFIG structure that is initialized by calling UCM_MANAGER_CONFIG_INIT.
Return value
UcmInitializeDevice returns STATUS_SUCCESS if the operation succeeds. Otherwise, this method can return an appropriate NTSTATUS value.
Remarks
This method initializes UcmCx and allocates resources required, registers for PnP events, and sets up I/O targets. The client driver must call this method in the driver's EVT_WDF_DRIVER_DEVICE_ADD implementation.
