+The returned output is a json-array, each element is a json-object describing
+a single device type.
+
+Each json-object contains the following:
+
+- "name": name of the device (json-string)
+- "bus": the name of the bus type for the device (json-string)
+    - Possible values: PCI, SCSI, I2C, ISA, SSI, USB, virtio-serial-bus, System,
+                        IDE, s390-virtio
+- "alias": an alias by which the device is also known (json-string, optional)
+- "description": description of the device  (json-string, optional)
+- "creatable": whether this device can be created by the user (json-boolean)
+- "properties": a json-array where each item is a json-object that describes a
+  property of the device. If the device has no property to be setup, this item
+  will not be present. Each json-object contains the following:
+     - "name": the name of the property (json-string)
+     - "type": the json type of the property (json-string)
+            - Possible values: integer, string, boolean
