I have 2*Phidgets LED 64 boards running my XPlane Overhead. They are working perfectly in XPlane 11. I have now added XPlane 12 but cannot get the Phidgets to light the Annunciator LEDs. I copied across the settings from XPlane 11. Even the LED on my Throttle Quadrant doesn't light and it is not run...

Got my problem sorted. Deep in my sim the power lead to the USB Hub (where the Phidgets Board was attached) had dislodged!! Now the board is alive again but I Still have problems. I will make a new post re that.

Have just come across this same issue today after years of no problems. Using a computer power supply as source - all other attached peripherals working fine.
