WDF_USB_DEVICE_INFORMATION structure (wdfusb.h)
[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
Size
The size, in bytes, of this structure.
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.
HcdPortCapabilities
This member is reserved for system use.
Traits
A set of bit flags that identify device traits. The flags are defined by the WDF_USB_DEVICE_TRAITS enumeration.
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.
