Hello everybody!
I've got some problem with bluetooth - time to time it stops responding and i get this in dmesg:

$ dmesg | grep hci0

Restarting device through bluetoothctl gives nothing, but 'hci0 link tx timeout'.
The only solution for now is to power off the PC and then to start it again. Rebooting makes nothing O_o
Is there any solution to make it work stable?
Thx in advance!

Fixed it by reloading the btusb module:

modprobe -r btusb
modprobe btusb

Seems to occur very seldom.

Hey, giving my contribution here, hope it helps as it is helping me:

I have the same issue since I bought a new usb dongle for bluetooth. But I am able to connect after a random number of tries restarting the bluetooth service, powering off and on the bluetooth, trying to connect, so I created this program [1] to do this boring work to me.

[1] https://github.com/mageddo-projects/lin … ection-fix

Using it:

$ bluetoothctl devices
Device 94:CC:56:E5:72:85 WH-1000XM4
$ java -jar linux-bluetooth-connection-fix.jar 94:CC:56:E5:72:85

About the bluetooth issue root cause:

I wasn't able to find a real fix for the bluetooth problem, looks like it doesn't even exist, all people advise to buy a new hardware at the end, then I made this program as a workaround.

Watch the age of threads; I hope they are not still looking for help six years later.

Closing this old thread.
