The WDF_USB_INTERFACE_SELECT_SETTING_PARAMS structure contains selection information for a USB interface.
SizeThe size, in bytes, of this structure.
TypeA WdfUsbTargetDeviceSelectSettingType-typed value that identifies a technique for specifying a device interface.
TypesTypes.DescriptorTypes.Descriptor.InterfaceDescriptorIf the Type member is WdfUsbInterfaceSelectSettingTypeDescriptor, this member contains a pointer to a USB_INTERFACE_DESCRIPTOR structure that identifies a device interface.
Types.InterfaceTypes.Interface.SettingIndexIf the Type member is WdfUsbInterfaceSelectSettingTypeSetting, this member contains an index value that identifies an alternate setting for the interface. (The interface is identified by an interface object handle that the driver passes to WdfUsbInterfaceSelectSetting.)
Types.UrbTypes.Urb.UrbIf the Type member is WdfUsbInterfaceSelectSettingTypeUrb, this member contains a pointer to a URB structure that describes a device interface. The URB structure's Function member must be URB_FUNCTION_SELECT_INTERFACE, and other members must be initialized as appropriate for the interface.
The WDF_USB_INTERFACE_SELECT_SETTING_PARAMS structure is used as input to the WdfUsbInterfaceSelectSetting method.
To initialize a WDF_USB_INTERFACE_SELECT_SETTING_PARAMS structure, your driver must call one of the following functions:
