Rpi4B with Volumio doesn't see Audiophonics U-Sabre DAC

Hi, had any of you guys a problem with mounting Audiophonics U-Sabre to Rpi with Volumio? I’ve checked Rpi via SSH and it tourned out it does not see my DAC. To make sure USB ports are ok, I’ve mounted pendrive to all 4 of them and it was visible each time. 2 ports are 2.0 and two 3.0. I really hope someone had similar problem cause I ran out of ideas.

Cheers :slight_smile:
