-``HubInit()`` automatically connects to any of the known hubs and reports its features in ``hub_info``
-The init loops over all the available ports and ``ConnectToDevice()`` connects with available devices.
-The remote, if there is one, controls 2 variables; in range(-100,100), the other in range(0,100).
+``HubInit()`` automatically connects to any of the known hubs and reports its features 
+in ``hub_info``.
+``GetPorts()`` and ``ConnectToDevice()`` are used to connect any available device.
+The later also initiates a class object belonging to that device.
+A remote can control 2 variables; CH A/1 in range(-100,100) and CH B/2 in range(0,100).
 These could be used to control 1 or more motors, lights, etc.
-On ``DIAGNOSTICS_PERIOD`` 4 different sensors values are read if available together with hub voltage and current. 
+On ``DIAGNOSTICS_PERIOD`` IMU and 4 different sensors values are read if available.
+Also hub voltage and current are printed at that time.
 Also ``ch1_val`` is applied as dc() value on motors if there are any.
