Have same problem as you desribe, i use a Skywatcher AZ-go2, but i cant connect with the synscan or the synscan beta even if i do a 3 point allignment and my cable is fine.
so for now i use skywatcher virtuoso driver it works in testing inside, but with no tracking
I tried the Eqmod driver every things works on that exept it cant goto where it was supposed to,but probably thats because its meant for EQ mounts.
it can run using ascom,stellerium,synscan app and sharpcap on my labtop,but i wanted a sollution so i could be inside and project it on my tv but its a big problem tracking doesnt work
