Since nearly a year I have the Digiface AVB and even though the Mac supports AVB native I always liked this little box. (Never failed, Lower latency and Totalmix).
Today I tried to use it the first time on a different laptop (Mac OS 10.14.6 on a 13" Macbook Retina, 8 GB RAM, 256 GB ssd, by the way: this is a company computer with a custom loadset, however I have administrator rights and everything besides iCloud and executing code from unsigned developers work...)
When I connect the Digiface AVB to the Macbook via USB-c to USB 3.1 B cable the Digiface starts blinking and for a second and then the blue USB light turnes on. But the computer doesn't do anything. (No AVB Contoller.app starts and the system report says that there is no USB device connected, even the RME FUT tool doesn't even start :-()
What can I do? I downloaded the new drivers and the latest control.app; and it works on all other Macs (2 Mac Pro, a MacBook Pro and an old Macbook Air)
