The device and the USB drivers should be ok as confirmed using Psychtoolbox on Ubuntu and Xidon2
When registering the extension, I get an error (also when running Presentation as Admin), see Screenshot left
OK, uncheck “Don’t register server with Windows” as per the instructions, see Screenshot middle
After right-click → enumerating devices in Presentation, I get Screenshot right (had to combine Screenshots because Forum software does only allow one upload for first posts).
Hi Hisham, this suggestion didn’t work for me. Can you suggest anything else please? Brand new RB-844/RB-540 just not registering with Presentation. I’ve tried everything suggested from Cedrus support, but still no joy re-enumerating the devices. Devices are fine as tested wtih Xdion 2.

Presentation: v23 Build: 10.27.21
Cedrus: RB 844 and RB 540
I’m not sure what else to suggest, honestly. Have you contacted NBS for support? I would be happy to have a 3-way screen sharing via Zoom to help resolve it.
Hi Hisham, I got it working now. I installed older versions of Presentation incrementally (backwards, uninstalling as I went), testing the extension each install and on v18 it worked. I then re-installed the latest version v23 Build 10.27.21 and removed the extension added in v18 and re-added it and it worked a treat. I hope this solution is helpful for others.
All the best,
Colin
