PUSB_BUSIFFN_GETUSBDI_VERSION callback function

Description

The GetUSBDIVersion routine returns the USB interface version number and the version number of the USB specification that defines the interface, along with information about host controller capabilities.

[!NOTE] USBD_IsInterfaceVersionSupported replaces the GetUSBDIVersion routine. To determine the capabilities of the host controller and the underlying USB driver stack, call USBD_QueryUsbCapability.

Syntax

typedef VOID
  (USB_BUSIFFN *PUSB_BUSIFFN_GETUSBDI_VERSION) (
    IN PVOID,
    IN OUT PUSBD_VERSION_INFORMATION,
    IN OUT PULONG
  );

Parameters

unnamedParam1 [in]

Handle returned in the BusContext member of the USB_BUS_INTERFACE_USBDI_V0 structure by an IRP_MN_QUERY_INTERFACE request.

unnamedParam2 [out, optional]

Returns the host capability flags. Currently, no host capability flags are reported.

unnamedParam3 [out, optional]

Returns a pointer to a USBD_VERSION_INFORMATION structure that contains the USB interface version number and the USB specification version number.

Remarks

The function returns the highest USBDI interface version supported by the port driver. This function replaces the USBD_GetUSBDIVersion library function provided by usbd.sys.
