Topic: Device unaviliable on BigSur 11.6 on intel

Hello RME team!
I have a problem with Babyface Pro FS on iMac Big Sur 11.6 Intel
I bought it in Moscow from this retailer https://kbmusicstudio.com
I've installed the drivers properly and allowed all the security changes.
But still i can get no sound.
Total Mix can not show up on the screen. When I launch it nothing appears on the screen (I have only one screen). Same for Fireface USB settings app.
And another strange thing. When I change OUT setting on the card to CH 1/2 I can see the indicators pumping. And when I switch to Phones (I do not have monitors right now) I do not see the indicators.
My serial number is 73021333
I've tried both 3.27 and 3.24 versions of drivers
I've also added TotalMix and Fireface USB apps to Accessibility in security settings.
Please help.

Please see rme.to/mace and https://forum.rme-audio.de/viewtopic.php?id=33277
Also make sure the unit is not in Class Compliant mode.
