For more info, see. The framework represents each USB device as a framework USB device object. A UMDF driver must create a framework USB device object before the driver can access the framework's support for USB I/O targets. UMDF provides USB device object methods that enable a UMDF driver to: • • • • Creating a UMDF-USB Device Object To use the framework's USB I/O target capabilities, a UMDF driver must first obtain a pointer to the interface. To obtain the pointer, the driver must call the QueryInterface method of the device's interface. The following code example shows how to call QueryInterface to obtain the pointer: hr = pdevice->QueryInterface(IID_IWDFUsbTargetFactory, (LPVOID*)&ppUsbTargetFactory); The driver must next call the method to create a USB I/O target object for the device.

After the driver creates the USB I/O target, the driver can send requests to the I/O target. Typically, drivers call IWDFUsbTargetFactory::CreateUsbTargetDevice from within an callback function. After the driver calls IWDFUsbTargetFactory::CreateUsbTargetDevice, the driver can (for example, USB descriptors for the device, USB interfaces, and interface endpoints). The USB descriptors are described in the USB specification.

Obtaining UMDF-USB Device Information After a UMDF driver calls the method to create a UMDF-USB target device object, the driver can call the following methods that the USB target device object defines for obtaining information about a USB device: Obtains a device's USB device descriptor. Obtains the number of USB interfaces that the device supports.

Obtains a pointer to a interface that exposes one of the USB interfaces that the device supports. Retrieves capability information that is associated with a USB device. Retrieves a WinUsb power policy. Obtains the WinUsb interface handle that is associated with the I/O target device object.
