Hi everyone,

I’m having trouble with Bluetooth on my Fedora 41 Workstation. It is not turning on. I’ve tried all the basic troubleshooting. I can ensure that device is alright, and works on Linux 6.10

  • Kernel Version: Linux 6.12.4-200.fc41.x86_64
  • Bluetooth Device: CSR8510 A10 (usb dongle)

Additional Information:

~$lsusb
Bus 005 Device 002: ID 10d7:b012  CSR8510 A10

~$ bluetoothctl
[bluetooth]# Agent registered
[bluetooth]# power on
No default controller available
[bluetooth]#

Any help or suggestions would be greatly appreciated. Thanks in advance!

Hi,
Same issue. Just reboot and select the earlier kernel. Or do:

sudo dnf downgrade kernel

Then reboot and select the earlier kernel. Next time you get an upgrade it will probably be fixed.

If bluetooth is “mission critical” for you, it is worth spending a small amount of money to purchase a dongle with good linux support for use when an older USB BT device acts up.

The LHDB probes that found your BT dongle show “detected” more often than “works”, even for older distros.

It was supposed to be fixed on 6.12 update. But, still no improvement

It is hard to find a supported product in India at budget. TP-Link BT adapter is available, but not sure if it will be working or not

6

In N. America, TP-Link UB400 and UB500 USB Bluetooth adapters are supported by kernel drivers, but specs vary by region. Try to get the USB ID and then use the LHDB to see if it works for other linux users.

Currently, the only known workarounds for Bluetooth issues are:

  • Downgrading to a previous kernel version: You can try reverting to kernel version like 6.10.6 or an earlier compatible version. This might resolve the Bluetooth problems you’re encountering.
  • Using a supported Bluetooth dongle: Consider purchasing a Bluetooth dongle that is known to be compatible with linux. This can often provide a stable and reliable Bluetooth connection.
