Hi Jassem, thanks for the response.
Good to know that the 2nd scenario should work. I did not see a reaction from the focuser. However, in the meantime I double checked and apparently I missed that the focuser is triggered only once when the joystick button is pressed, rather than keeping to focus in or out as long as it is held. So it works in principle, but it may be quite hard to manually focus that way. Unfortunately it is not recommended to have the aux connection active while the focuser is controlled via the serial port, so the hand controller can not be used for manual focusing in that scenario. 
To your knowledge are there any plans to add joystick focuser options to the nexstar driver? Or alternatively focuser support to the Aux driver?
