Hi guys, I need your help as a newly user of linux. I have a problem with bluetooth adapter and honestly I tried all of guides to solve it in this forum and from much different somewhere. Unfortunately, i couldnt solve and i realy need your help.
Adapter is Railink3290 and the error says no default adaper controller available. Thank you for your help.
Hi @Emre, and welcome!
There are drivers for the Ralink 3290 in the AUR:
$ pamac search 3290
[...]
rtbth-dkms 3.9.6-1 AUR
rtbth Kernel module sources for Ralink RT3290 bluetooth, lomiu's solution.
[...]
So, you can install them using:
pamac build rtbth-dkms
Hope this helps!
Thanks for the advice but sadly it doesnt help 
In that case, please provide some additional information:
Maybe there is some info would be usefull to find the problem.

Edit:
I don’t know if this’ll work, as I don’t use bluetooth, but try:

Well, as I’ve mentioned, I don’t use bluetooth. So don’t really know anything about it. However, this 
Looks like the opposite of what you want to do. Because, rmmod removes a kernel module:
So all I can suggest is, reinstall the driver, restart and test again.
Aha, okay that’s solved. The problem is about rmmod and i stopped this command and now it’s working. you can not imagine how many days im looking for any solution for that but it’s really funny because of that was so much easy just because of rmmod. Thank you so much @Mirdarthos
