I’m using Standard Standalone PsychoPy v3.2.4 with a Cedrus button box (RB-740) on MacOS, Version 10.14.6.
I have an experiment that uses the response box on two separate routines. When I attempt to run the experiment I receive the error: “Could not find a Cedrus device”. If I disable the response box object on one of the routines (for testing), the experiment runs fine. From reading online it seems there is a known issue of attempting to have multiple response box objects in the same experiment. I need more than one routine to allow a testing block before the experimental block.
Does anyone know of a solution/work-around for this problem?
Thank you for any help you can offer,
