USBD_BuildRegisterCompositeDevice routine
The USBD_BuildRegisterCompositeDevice routine is called by the driver of a USB multi-function device (composite driver) to initialize a REGISTER_COMPOSITE_DEVICE structure with the information required for registering the driver with the USB driver stack.
The routine is called by a driver that replaces the Microsoft-provided composite driver, Usbccgp.sys.
Syntax
void USBD_BuildRegisterCompositeDevice(
_In_ USBD_HANDLE USBDHandle,
_In_ COMPOSITE_DEVICE_CAPABILITIES CapabilityFlags,
_In_ ULONG FunctionCount,
_Out_ bcount(Size) PREGISTER_COMPOSITE_DEVICE RegisterCompositeDevice
);
Parameters
- USBDHandle [in]
-
A USBD handle that is retrieved in a previous call to the USBD_CreateHandle routine.
- CapabilityFlags [in]
-
A caller-allocated COMPOSITE_DEVICE_CAPABILITIES structure that indicates the capabilities that are supported by the composite driver. For instance, to indicate that the composite driver supports function suspend, set the CapabilityFunctionSuspend member of COMPOSITE_DEVICE_CAPABILITIES to 1.
- FunctionCount [in]
-
The number of physical device objects (PDOs) to be created by the parent driver. The FunctionCount value cannot exceed 255.
- RegisterCompositeDevice [out]
-
A pointer to a caller-allocated REGISTER_COMPOSITE_DEVICE structure. Upon completion, the structure is populated with the specified registration information. To register the composite driver, send the IOCTL_INTERNAL_USB_REGISTER_COMPOSITE_DEVICE I/O request and pass the populated structure.
Return value
This routine does not return a value.
