I have a similar problem. I’ve elected to post in this topic however I’m quite happy to start a new topic if the Moderators would prefer.
I recently purchased the CLS-E NG Force Feedback Yoke and CLS-E Rudder. Initially I only connected the yoke but later the rudders via the CAN bus to the Yoke which is connected to the computer by the USB. I have read the documentation a number of times and believe the current installation has been done correctly. However, in troubleshooting I’ve made many changes, uninstalls and reinstalls. Currently I have the hardware connected as described. I wish to use the force feedback features and therefore have unistalled vJoy and instead using CLS2SIM. CLS2SIM sees all the hardware, roll, pitch, rudder pedals as force feedback devices and the brakes as analogue devices. However, CLS2SIM cannot seem to connect to X-Plane. (Yes it is on the runway.) The plugin is showing as active in X-Plane.
X-Plane can see the pitch and roll control as well as at least some of the yoke buttons, even when CLS2SIM is NOT running. X-Plane has never seen the rudders or brakes.
Win10 1903, CLS2SIM 4.23.3 Beta, X-Plane 11.36r2, XPlane10 Connector v6.2.3, vJoy 220.127.116.11 (when installed).
