REGISTER_COMPOSITE_DEVICE structure

The REGISTER_COMPOSITE_DEVICE structure is used with the IOCTL_INTERNAL_USB_REGISTER_COMPOSITE_DEVICE I/O control request to register a parent driver of a Universal Serial Bus (USB) multi-function device (composite driver) with the USB driver stack.

To initialize the REGISTER_COMPOSITE_DEVICE structure, the composite driver must call the USBD_BuildRegisterCompositeDevice routine.

Syntax


typedef struct _REGISTER_COMPOSITE_DEVICE {
  USHORT                        Version;
  USHORT                        Size;
  USBDI_HANDLE                  Reserved;
  COMPOSITE_DEVICE_CAPABILITIES CapabilityFlags;
  ULONG                         FunctionCount;
} REGISTER_COMPOSITE_DEVICE, *PREGISTER_COMPOSITE_DEVICE;

Members

Version

The version of this structure. USBD_BuildRegisterCompositeDevice sets this member.

Size

The size of this structure. USBD_BuildRegisterCompositeDevice sets this member.

Reserved

Reserved. USBD_BuildRegisterCompositeDevice sets this member.

CapabilityFlags

The capabilities that are supported by the composite driver. To specify that function suspend is supported by the composite driver, first initialize the COMPOSITE_DEVICE_CAPABILITIES structure by calling the COMPOSITE_DEVICE_CAPABILITIES_INIT macro. Then, set the CompositeDeviceCapabilityFunctionSuspend member of COMPOSITE_DEVICE_CAPABILITIES to 1. Finally, call USBD_BuildRegisterCompositeDevice and pass the initialized structure in the CapabilityFlags parameter.

FunctionCount

The number of functions supported by the composite device. The FunctionCount value must not exceed 255.

Requirements

Version

Windows 8
