Argus 2e not working with 0.6.2 but with 0.4.0

[Barni61]

I was able to get a stream from my Argus 2e using neolink 0.4.0.
Drawback is that the battery was low after short time.
So I found 0.6.2 here and this offers a battery saving option.
For whatever reason, I don't get any stream and no error :(
Is there a debug option, which I didn't found?!
