Ubuntu 20.04 and Desktop Video 12.4

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.
