I have the new MAC Pro and I installed Adobe Premiere Pro CC 2014 few days ago.
I have the UltraStudio 4K by BlackMagicDesign connected through ThunderBolt.
BUT...
Premiere Pro CC cannot add it to the device control.
Moving this discussion to the Hardware forum.
Did you install the UltraStudio Device driver before Adobe Premiere Pro CC 2014 or after it ?
