Audiofuse buffer stuck at 512 samples

[Trond]

My Audiofuse interface have suddenly started to behave weird. I am mixing huge project, so I wanted to set the buffer to 1024 samples. But ... when I try to change it inside Ableton preferences from 512 to 1024, it goes back to 512 after a second or less.

Have tried the following:
* Change buffer inside Audiofuse control center. Same happens.
* Turn off safe mode. Same happens
* Uninstall and reinstall Audiofuse Control Center. Same happens.
* Did reset Audiofuse. Same happens.

Then I tried Asio4All as driver. The result? No problem to get Audiofuse stick to whatever buffer size I set it to. I think it is safe to say it is a Audiofuse driver problem. What to do?

My system:
HP Elitebook 8570P
Windows 10 Home with all the latest updates
Ableton Live 10.1.9 (the latest version)

Well, when I change it in Asio4All, it will not change on the unit. In the preferences in Ableton it says the buffer is 512 samples, even if Asio4All says it is 1024 ...
