AR MKI overbridge latency fault

Since I have updated my MKI and the overbridge to the new versions, Overbridge Engine gives me a latency error message and it´s not connected.
I have tried several USB cables (without connecting to a hub) but I can´t find a solution.

I have the same problem here

I have the same problem and it’s only with the AR Mk1. I have two A4 Mk1, one AH Mk1, one DT an one DN with no issues. Only the AR give me problems even if plugged alone.
On OSX 10.12…
