Syntax
NTSTATUS UcmUcsiDeviceInitialize(

);
Parameters
WdfDevice
A handle to a framework device object that the client driver received in a previous call to WdfDeviceCreate.
Config
A pointer to a caller-supplied UCMUCSI_DEVICE_CONFIG structure that is initialized by calling UCMUCSI_DEVICE_CONFIG_INIT.
Return value
