Bluetooth not working after restart

My Bluetooth does not work on the boot. I tried many things but none of them worked. Now after I reboot, I have to first

sudo modprobe -r btusb

and

sudo modprobe btusb

then my Bluetooth is back (solely "sudo modprobe btusb" does not work).
I guess the Bluetooth was loaded but blocked, any help?

Re: Bluetooth not working after restart

Does dmesg report module loading failures or errors about bluetooth functionality?

What is the output of systemctl status bluetooth.service?

It is

Your are right, there are some load errors.

And the dmesg

There is a timeout error.

Re: Bluetooth not working after restart

Don't grep the output. It's likely to exclude crucial context. Not to mention all lowercase occurrences. Also post lsusb output.

Re: Bluetooth not working after restart

I ran into this exact same issue, same error messages.

My solution:

    sudo vi /etc/bluetooth/main.conf

    Experimental = True
    KernelExperimental = true

Reboot, confirm systemctl status bluetooth.service is running, bluetooth fixed.
