My house has been hit by lightning strike.
The internet box died
My PC motherboard died and probably the Cpu. The power supply is OK as it runs know in a anew PC.
The PC was connected to the box by Lan wire. Other PCs were connected to an additional switch and they didn’t suffer.
So I replaced the PC and guess what? The simucube and Ascher button plate are not detected anymore while my pedals set and shifter are still working.
So here is the troubleshoot on my Mige1010 / simucube / ioni pro hc:
the PSU is working
the sync is working as I can see the wheel moving as before when I power on. And I can hear the sound in the motor after the sync.
