[Intel 9560] Bluetooth doesn't turn on

[Brieuc du Garay]

UPDATE
======

I tried another kernel (`5.4.0-40-generic` and it didn't worked.
Trying to reboot (and get back to the latest kernel) it didn't shutdown, so I hard shutdown it, and restart with the `5.4.0-42-generic`.

And now, it works.
I hope the logs below may help you to find out what happened, and help others to fix their issue if it's similar to this one.

Hello,

For now, everything worked fine, until this morning when Bluetooth stop working.

Ubuntu 20.04

**What expected to happen :** Bluetooth turn on on start, and if it's off it turns on when I turn it on.

**What happens :** it doesn't turn on.

```

This sounds like Bluetooth hardware malfunctions until a full reset (or completely powered off).

[Brieuc du Garay (bree29)]

@alexhung That's what I thought, even if I did tried powering off my laptop and unplug the charger for several minutes. Yet, I didn't take off the battery.
I did happen again few days ago, althought that time a simple `shutdown -r now` was enought to get it to work.

You can also try the unload & reload Bluetooth driver by "sudo modprobe -r btusb ; sudo modprobe btusb". It may save you some time.
