New Simucube 2 pro turns off at startup

I just purchased a Simucube 2 pro but I am having issues with getting it to work.

I installed Simucube Tuner and initially the unit powered on without a problem. However, after I enabled high torque mode I started getting problems and now the unit shuts down a second after turning it on.

I tried reconnecting all cables, bought a powered USB hub but the issue remains. I also tried connecting the unit to other power sockets and tried using another USB cable.

If I start the unit without the torque button connected or pressed in, the unit does keep its connection but the software doesn’t recognise any inputs.

As soon as I release the torque button the wheel immediately loses power.

I tried downgrading to True Drive and downgraded the firmware but this doesn’t solve the issue.

In True Drive I get the following error message: Motor Faults (cycle E-stop to clear): Power Stage Forced Off Fault Location ID: 440205

Any ideas what the problem could be? Faulty power supply?

I would advice to make a support ticket at Simucube.com.
