Disconnect the hub and all other none essential USB devices.


Restart the Mac Studio in Safe Mode followed by a normal Restart and test your USB devices one at a time.


Then if the Delock hub does not work...?

1) Contact Delock for support and/or a replacement.

2) Replace that USB 2.0 hub with USB-C 3.2 hub or TB dock.
