System Settings and Hints
Our tests have shown that the Sonnet Thunderbolt 3 Extender Box (Sonnet Echo Express SE III) is currently not usable under Windows 11.
This is because of Windows 11 currently does not support multiple-slot Thunderbolt system expensions.
Using it under Windows 11 either not external hardware is shown or leads to system crashes.
Microsoft has announced such a support for Windows 11 23H1.
There is also a note from the Extender Box manufacturer about this:
