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
- 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.
