Hey,
After I changed my broken motherboard, I have problems to get my TB3 Docking Stations work. It works when I unflash my Titan Ridge to default, but then my system is running buggy with massive lags and system crashes. After I flashed my card, everything (Apollo Audio Interface and Blackmagic Ultrastudio) works except of my Docking Stations (I have 2 and tried both). We have tried everything the last 2 month but nothing helps. We tried different EFI settings, many fw, different slots and various BIOS settings. The Dock shows up in IOReg but does nothing and isn't shown up in OS under TBController. If I plug in a portable USB drive into the TB Slot, it works as well.
Maybe someone of you can help me to fix that?
thx
