_WDF_USB_DEVICE_INFORMATION structure

[Applies to KMDF and UMDF]

The WDF_USB_DEVICE_INFORMATION structure contains version and capability information for a USB device.

Syntax

typedef struct _WDF_USB_DEVICE_INFORMATION {
  ULONG                    Size;
  USBD_VERSION_INFORMATION UsbdVersionInformation;
  ULONG                    HcdPortCapabilities;
  ULONG                    Traits;
} WDF_USB_DEVICE_INFORMATION, *PWDF_USB_DEVICE_INFORMATION;

Members

HcdPortCapabilities

This member is reserved for system use.

Size

The size, in bytes, of this structure.

Traits

A set of bit flags that identify device traits. The flags are defined by the WDF_USB_DEVICE_TRAITS enumeration.

UsbdVersionInformation

A USBD_VERSION_INFORMATION structure that provides version information for the host controller driver (HCD) and the USB specification version that the device supports.

Remarks

The WDF_USB_DEVICE_INFORMATION structure is filled in by the WdfUsbTargetDeviceRetrieveInformation method. Before calling WdfUsbTargetDeviceRetrieveInformation, the driver must call WDF_USB_DEVICE_INFORMATION_INIT to initialize the structure.

Requirements

   
Minimum KMDF version 1.0
Minimum UMDF version 2.0
Header wdfusb.h (include Wdfusb.h)
