X1 MK3 Hub bricks Traktor / dead hub after 11 months

Suddenly after year of use integrated hub totally bricks Traktor.

Settings which was working till yesterday:

- Macbook Pro (OS latest, T4 latest) connected (with UDG USBC-USBB Cable) to X1MK3
- Z1 MK2 connected (with NI cable) to powered X1MK3 hub
- AUDIO 6 connected (with NI cable) to powered X1MK3 hub

Now:
- if is connected AUDIO6 microphone: icon blinks in menubar like crazy, USB led on AUDIO6 too
- if Z1 is connected, no soundcard is recognised

* in both examples is PLAY / CUE in Traktor extremely lazy, slow
* disconnectd turn Traktor back to normal flow
* connecting with same cables to small external usb hub - everything is OK
* tested: restart of T4 / restart of Macbook / unplug X1 powercord / reinstall T4 / complete uninstall T4+new install

! once i managed to make it work for whole day (i dont know how) but today is bug here again

Did after 11 months died USB Hub inside???
