I have a similar issue. The issue emerged after I used my CV inputs for the first time. And now Overbridge only works when I have CV inputs connected! Even though the inputs are off in my settings.
I have the same issue. I have my Analog Four since a while, but I am using it now for the first time with OB. When I connect the A4 with the original cable to Overhub or without Overhub it shows the same “measuring” status. When I then want to use it in the DAW, it suddenly fails. Red Fail Status and Windows gives me a message about a device failure.
I use Win 10 with OB 2.1.5.4 and A4 MKII with Firmware 1.51C
The Digitakt, Digitone and Syntakt work on OB. Just the A4 hasissues.
Edit: Oh! I haven’t seen that the thread is 3 years old. I hope it’s ok!? Maybe someone has still the same issue?
