bluez and bluez-utils is installed. And I am pretty sure that it worked the first time I put it in.
A different stick works.
My questions:
Any idea, how to resolve the problem?
Is there an easy way to find the driver (that is not google + AUR)?
Is there a way to get something like a list of all installed drivers?
I already did that. As said, another adapter is working, and I’m pretty sure that this adapter was working, too.
I therefore assume, that that driver must be somewhere in the main packages, and something else is wrong.
Or, I am insanely stupid, and used my old adapter while thinking it was the new one. But I really don’t think so, as my old adapter is very big, and the new one is very small, and I’m pretty sure that I changed it. And I remember beeing happy that the problems of my old adapter were not present. That’s why I’m so confused, that the drivers are apparently missing.
