Hi,

I have the same mount and I never use the handcontroller with Stellarmate or Kstars/Ekos. What you need is a EqMod cable (specific for your mount HEQ5 pro), one plug into the HC socket of the mount and the USB plug into the Pi or whatever you have.
And of course, you will use the driver Eqmod instead of Synscan or Synscan legacy.
