+ * udev_device_new_from_device_id:
+ * @udev: udev library context
+ * @id: text string identifying a kernel device

+ * Create new udev device, and fill in information from the sys
+ * device and the udev database entry. The device is looked-up
+ * by a special string:

+ * The initial refcount is 1, and needs to be decremented to
+ * release the resources of the udev device.

+ * Returns: a new udev device, or #NULL, if it does not exist
