Hi,
The problem:
We’ve been using a Cedrus C-Pod to send triggers to an antneuro eeg system. We’re running two seperate experiments, one using PsychoPy and one using Eprime and triggers were previously working great! We’re running these in Windows 10. Suddenly, with seemingly no changes, both experiments running on different softwares stopped sending trigger signals.
What we’ve tried:
(aside from unplugging and plugging back in and restarting the computer). Our first real clue was that, PsychoPy output told us that the C-Pod device was not detected, despite previously working great with the pyxid2 library which should auto discover the device. Since we use two different experimental softwares and our codes had previously been working, we felt it wasn’t a software issue. By unplugging and plugging back in our Cedrus C-pod while the computers were on we were able to get a trigger to appear in the ant neuro software, suggesting it’s also not a software issue on that end, and that the C-Pod (which still lights up) is working. We started to hone in on a problem when we followed the instructions about updating firmware and using Xidon 2 here. Namely, after following the first two steps Xidon still does not detect the device. Finally, in the device manager we know that the C-Pod is hooked up under USB Serial Port (COM6).
Where we need help:
My best guess is something is going on with the drivers or how the windows computer is finding the C-Pod, but I don’t exactly know where to start. What would you try from here or is there anything we haven’t tried yet? Any ideas why the C-Pod may have stopped being recognized in the first place? If we can provide any further information please let us know.
If we make progress I will post updates here in case anyone else runs into whatever issue this is.
