[Solved] Can't get Bluetooth dongle to work

Well, I will try to be direct to the subject here.
I bought a new Bluetooth USB dongle on Amazon and tried to get it working on my Arch Linux and yes, it didn't work, then I looked into these outputs:

lsusb

Also tryed dmesg: http://ix.io/2rEk Which gave me this info "Product: CSR8510 A10", Well, looks like an old kernel issue related to chinese faking some Bluetooth devices and there is a patch out there to make it work on newer kernels, so I built some kernels using this handy script https://gist.github.com/nevack/6b36b82d … 9124840a07  ...

Then tried a lot of patches:

http://ix.io/2rEl
http://ix.io/2rEn
http://ix.io/2rEo
http://ix.io/2rEp
http://ix.io/2rEq

Also added this line to the /etc/modprobe.d/csr-bluetoothdongle.conf

options btusb reset=1 enable_autosuspend=0

None worked... but guess what, it works fine if I try an old distro in Virtual Box like tested on Linux Mint 18.03.
Is anyone out there with a patch for me? maybe there is the right one out there.

Update:
Tried this updated patch:
http://ix.io/2rZn
Didn't work for me.

The problem is solved. Some updates added fixes for some fake bluetooth dongles and mine was included.

Re: [Solved] Can't get Bluetooth dongle to work

Oh, very nice!
I was closely following this issue on bugzilla.kernel.org, and I had the feeling it still wasn't working for your BT adapter.

And, it still doesn't work for me with the last ArchLinux kernel (5.8.13-arch1-1). Did you have to patch + build your own kernel?

Thanks a lot!
