conf file in home directory and run both sh and patch files?

i ran the script and patch files and pasted conf file in home directory. doesnt work yet. the bluetooth support button isnt working in garuda assistant

I've handled plenty of help requests on that dongle on other distros. The general conclusion was most of those CSR dongles are legit and they usually don't have issues, but others that are sold are cheap Chinese knock offs that don't use the same chip.

I'm not saying that's the case here, but I've seen enough of these problems with that adapter that I don't waste my time trying to get it working anymore. If it is one of the cheap knock offs your not likely to get it working in Linux.

Is the installation method I mentioned correct?

I would expect these options woud be set in:

 /etc/modprobe.d/csr-bluetoothdongle.conf
