It is the best cheap PLUG&PLAY bluetooth adapter by TP Link (UB400) Ver:1.0 in the market fully compatible with GNU/LINUX.
lsusb listing it as Bus xxx Device yyy: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode) .
BE AWARE OF OTHER FAKE C.S.R. ADAPTERS will not support — see kernel regression bug and Kernel Bug 60824 .
But I AM CONFIRMING As this adapter is original there is no issue in it. Though in jounallog you may find some harmless error :
usb 1-1: device descriptor read/64, error -71
Bluetooth: hci0: unexpected event for opcode 0x0000
can’t get device qualifier: Resource temporary unavailable ]
But just ignore it, with «my adapter» I can able to reproduce these errors with 3 to 4 machines and it just working fine.
You some people may know about
PipeWire is the most revolutionary futuristic appearance to Gnu/Linux for Audio.It is designed to replace the pulseaudio and JACK.
It comes with support for LDAC, aptX, AAC, HSP/HFP, SBC, A2DP and many more with maximum hardware support by default, so just install PipeWire and your bluetooth wireless head will be working flawlessly with mic support natively wit this TP LINK UB400 BT adapter. But at the moment of writing PipeWire is at its super busy development phase so it might break things so beware. For any debian based distros, install it from — pipewire-debian PPA
I am attaching product photo and some kernel logs to prove the support under linux.

Bluetooth not working often in 20.04
Some of the answers work sometimes, and sometimes a combination of them and rebooting my system seem to magically help.
Symptoms of my earphones not connecting through bluetooth anymore:
- Using the GUI, while clicking on the connect on/off button to turn it on, it inmediatelly turns itself off.
- Using bluetoothctl, removing the device, trusting the device again and trying to pair just goes on until it fails due to my device turning off being so long trying to pair.
Might be related to some of these packages:
I’d like help in debugging this problem, I guess I’m tired of rebooting a few times every few days just to get my earphones working.
Edit: I’m using the tp link ub 400 bluetooth adapter.
