Hi, I'm facing this issue when my bluetooth dongle does not work in linux.
I'm not much handy when it comes to doing complicated things in linux,
messing with the kernel and stuff like that. I can't find information on

how

quoted

to use this patch and also what is the actual patch. 

My adapter id is the following: 0a12:0001

When I try to turn on bluetooth with bluetoothctl I recive this output: "no
default controller available"

and the output of hciconfig is the following:

hci0: Type: Primary  Bus: USB
      BD Address: 00:1A:7D:DA:71:12  ACL MTU: 679:8  SCO MTU: 48:16
      DOWN 
      RX bytes:367 acl:0 sco:0 events:12 errors:0
      TX bytes:37 acl:0 sco:0 commands:12 errors:0

I can't turn it up :(

English is not my first language so I'm sorry for any grammatical error, if
anyone could guide me in how to start and how to apply the patch I'd be on
your debt

I also can't get it to work even with the patches, but the patch should be
already available by default starting from linux 5.14.

To know your kernel version, just type in a terminal

uname -r

If your kernel is older than version 5.14, you can try updating your distro
or trying another with a more recent kernel like Fedora or Manjaro. You can
simply boot with USB without installing and test your Bluetooth dongle.

I've been using fedora 34, and there was no use, yesterday I updated to fedora
35 and the issue remains. I try using manjaro in live usb mode but is the same,
I can't get it to work. My kernel version 5.14.10-300.fc35.x86_64
