In the Menu you have a wrench, Look for USB connection, my SLR have 3 options: Mass Storage, PTP and Remote computer, when I set
PTP I get the same message than yours.
Now , I set Remote computer but now i get this message in EKOS:
[WARNING] Shutter speed widget does not have any valid data (count=0). Using fallback speeds...
I have attached the full log for that session. Please note i was only trying to see in the A55 would work so it is the only device in the profile. I know i can control my HEQ5 mount. Log just created!
The driver crashes, are you using INDI Nightly or Stable PPA? Please try Nightly PPA and see if it crashes there. If this is already nightly then we'll have to debug.
