My Bluetooth Adapter is not working

[RenanZ]

II bought the Barrot Bluetooth 6.0 adapter, but I can't activate it. The service is active on Zorin OS 18, but the button to activate doesn't turn on for some reason. There's a way to solve this problem in Zorin? Thanks

I tried to use this command:
dmesg | grep -i 'bluetooth|firmware|33fa'

It returns this, if it's useful:

I assume you are on Z18 Core?

From a websearch using: "Barrot Bluetooth 6.0 adapter ubuntu 24.04" I can find no solutions, only some references to no driver available.
As Z18 is based on Ubuntu 24.04, you may have better luck if you try a websearch yourself using that search-term or similar.

[Ponce-De-Leon]

• Did You take a Look at the ''Additional Drivers'' Tab in software & Updates if there is a Driver offered?
• Did You checked the Manufacturers Website if there are any Instructions for using the Adapter with Linux?
• Could You post the Output of sudo lshw -C network and rfkill list please?
• Are Secure Boot and Fast Boot in BIOS disabled?

[RenanZ]

• Yes i looked to the aditional drivers, and it does show that there's no aditional drivers
• Yes, i checked the manufacture website, there's no native linux drivers, only for windows 11
• Its in Fast Boot, not in Secure Boot
• Here the result of sudo lshw -C network and rfkill list:

@RenanZ

Its in Fast Boot, not in Secure Boot

Does that mean that Secure boot is disabled and Fast Boot not? If yes disable Fast Boot, too please.

The Adapter is a USB Device I guess? If yes plug it in and type in the Terminal lsusb and post the Output here.

Hi, no guarantees but you might need the bluetooth 6 packages via Synaptic - see my Tutorial Guide for Bluetooth 5.4 here:

Bluetooth device ASUS USB-BT540 on Zorin 17.3

Recently purchased one of these from Amazon (the clue is in the model number, it uses BT 5.4) [image] A few tips first. Make sure you have all these packages installed using Synaptic Package Manager: [image] [image] Next, make sure you have a wired USB mouse while you setup your Bluetooth Mouse. This is to enable you to click on the device in settings to Connect: [image] For connecting the USB Mouse (I have a Mk1 Cherry DW-9000 slim keyboard and mouse), it was just a case of switchin…

[RenanZ]

So, I don't know exactly if my BIOS has this option (My motherboard is Asus Prime B450M-Gaming/BR). It just has two options: Secure Boot and Other OS. There is no other option, sorry I guessed it was the same option.

[Ponce-De-Leon]

Okay, then I guess it is fine. What is with:

Actually, my bluetooth brand is Unnlink, i don't know if this is related but here is the result of lsusb:

BARROT Bluetooth 6.0 Adapter

like in Your initial Comment:

@RenanZ

II bought the Barrot Bluetooth 6.0 adapter

[Forpli]

Here it is written that the Barrot adapter works with kernel 6.17.8
So you could try to install a later kernel, e.g. mainline or liquorix.

https://www.reddit.com/r/openSUSE/comments/1oeao39/bluetooth_60/?tl=en

[HOW TO] Easily install a later Kernel (Needs Net Connection)

Updated as of Mar 28 2025 To install the Mainline Installer: add the repository: sudo add-apt-repository ppa:cappelikan/ppa Update sources and install: sudo apt update && sudo apt install mainline Launch Mainline from App Menu or terminal, and select the kernel you wish to test. To use TuxInvader Kernel: These are not Microsoft signed, so Secure Boot must be disabled in BIOS Settings. Add repository: If using Zorin OS 16: sudo add-apt-repository ppa:tuxinvader/lts-mainline If usi…

Disable secure boot and fast boot in your BIOS and if you have a Dualboot with Windows also disable fast startup in the energy settings of Windows.

[RenanZ]

So, i tried to update kernel to this version, but Zorin OS crashed

[RenanZ]

The Brand is Unnlink

[slm020]

I'd been struggling a lot with my bluetooth dongle. It is from uGreen but with a Barrot chipset apparently.

I spent a couple of hours working with Claude AI and it turned out that patching my kernel with this:

https://raw.githubusercontent.com/Seven0492/kernel-patches/main/cm749.patch

fixed it. Once it was done, the bluetooth dongle stayed on without those hci_i timeouts. Connecting devices seemed to work better through "blueman" which was found in the apt packager.

I tried through Fedora too, which it didn't work, but at least I'm all good in Zorin and can game with my xbox controller now

@RenanZ

33fa:0012

Using your hardware ID I searched with Perplexity search engine on zen browser and it came back with:

"That USB ID corresponds to a Bluetooth adapter that is supported by the standard in‑kernel Bluetooth USB driver on modern Linux.

What driver it uses

For USB device 33fa:0012, Linux uses the generic Bluetooth USB host controller driver, provided by the btusb kernel module, which is part of the mainline kernel. On any reasonably recent distribution (kernel 5.x or newer) this module is built in or auto‑loaded, so you normally do not need a separate vendor driver.

​

How to check and enable it

On a running system, the usual steps are:

• Run lsusb to confirm the device appears as 33fa:0012 and is labeled as a Bluetooth (BT) or “USB2.0-BT”-type adapter.

• ​

• Run lsmod | grep btusb and, if missing, load it with sudo modprobe btusb; if this succeeds, the adapter should show up in bluetoothctl list or your desktop Bluetooth settings."

Thanks man, but it doesn't work
