Hi JR,
Thanks for staying with this.
Any Saitek or other controls that I connect do register and work OK in X-plane; only the PFC controls don't register (they used to). The PFC controls do still work perfectly in FSX and P3D, although both these use special drivers developed for PFC for FSX/P3D simulators only, by Pete Dowson. I assume X-plane must incorporate something similar for PFC controls, as they did work in X-plane and PFC claim that their devices are compatible with X-plane. It seems possible that the X-Plane 'driver' has stopped working for me, despite re-installing from the original X-plane 10 disk and trying the controls unsuccessfully with this version.
The USB to Serial adapter is 'Brainboxes' US-101B for an RS232 connection. Windows 7 doesn't show PFC devices as such under 'Devices' or in 'Device Manager', which does however show the 'Brainboxes' device and to which COM port it is connected. I have tried this same port in X-plane without success as well as switching between all of the 20 port options listed in the X-plane PFC equipment section.
I have started X-plane with and without any controls connected and then re-connected, but without success for the PFC controls. The other controls are 'happy' either way.
I hope this information helps and please stick with this problem JR, since these PFC controls have worked well in the past in X-plane.
Thanks again,
Bill
