Dear all,
Please allow me to jump in the discussion. I am using Psychopy 3 (last version) on windows 10 64 bits. I had the same problem with Eyelink 1000, that I could finally fix this morning thanks to Sol response (thank you so much!).
My problem now is that I am preparing an experiment for an Eyelink 1000 plus (with a laptop host), and I was not able to use ioHub so far (even after fixing the lines 400 and 401 in eyetracker module). Running the demo gives me the folowing error message :
##### Running: C:\Program Files\PsychoPy3\lib\site-packages\psychopy\demos\coder\iohub\eyetracking\selectTracker\run.py #####

RuntimeError: Error starting ioHub server
ioHub Server Process Completed With Code: 1
I also have the same message using a minimal script for starting ioHub server (I initially described the problem here: Error with ioHub demo for Eyelink). Is there anything special that I have to do to use Eyelink 1000 plus ? maybe something to change in the yaml file or some settings on the Eyelink laptop host ?
Thank you so musch for any help !
