Today, we had twice an issue where the projector and its controller were not detected by Windows. The symptoms were that calls to Datapixx in Matlab/Psychtoolbox were not working, and/or it was not displaying on the projector (though maybe that’s a different issue). The stim computer USB ports are known to be problematic (hardware issue) and I will eventually replace that computer, but for now, the fix is to restart the stim computer. One can quickly check if the VPixx devices are detected with the program VPUtil (now linked on the desktop). When you open it, it will either show the detected devices, or complain that none were found.
Last week, there was also an issue with sound. Perhaps it’s related and the sound card is not detected. I’d recommend trying to reboot the computer if that happens again, and checking if the sound card is detected, e.g. in the device manager.
As always, keep me informed of any problems, and don’t hesitate to reach out anytime, via email, Slack or phone.
