And why did I changed GPSD at all?
as initially it was not working at all, gpsmon was simply empty, - now it shows something (at least!) and all these steps I wrote, were offered on Indi for astroberry or other sites for rPi.
P.S.
On windows, I was able to get data coming via its own software, but was not able to link it to EQMOD or SGP.
Anyway, - nice to know it should work almost out of the box
