Blackmagic Forum

Hello,
i installed Desktop Video 12.4 on two different ubuntu 20.04 computer, both with Thunderbolt 3.
I can see the device

Code: Select all

tbtadm devices
0-1     Blackmagic Design       Ultrastudio HD Mini     authorized      in ACL

I can see the drivers loaded

Code: Select all

blackmagic            630784  0
blackmagic_io        2056192  0


but in Desktop Video Setup there are no devices detected.
Ps. DesktopVideoHelper is running in background

Any hint?
Thanks for your help

I've had issues with Intel NUC Thunderbolt and BMD. Turn off all the Virtualization stuff in the BIOS.

Thnaks! will try

Just wanted to provide references to more people with similar issues. Turning off virtualization indeed fixed the driver issue. It only applies to systems where thunderbolt devices have already been detected in the system.
