As a workaround I'm currently doing rmmod btusb && modprobe btusb after
every boot which seem to do the magic. Attaching the dmesg for that just
in case.

Still failing with the same error on latest Eoan (kernel
5.3.0-40-generic). Dmesg with default kernel and usbcore.dyndbg=+p
attached.

Hi, sorry for the very late response.
This now appears to be working with the stock kernel. I'll post version details
later

Can you please boot Ubuntu with default kernel, and with kernel
parameter `usbcore.dyndbg=+p`, reproduce the issue, and attach dmesg?
Thanks.

I re-installed the default kernel using the following command:
$ sudo apt install --reinstall linux-image-5.0.0-20-generic
then installed the latest linux-firmware as directed above,
and now bluetooth is broken again, same as before. I guess this means that your
fix is required Kai-Heng.
Thanks
The custom kernel has a fix for this particular issue. Please use the
default kernel to test latest firmware.

Thanks Kai-Heng,
I installed the latest firmware as you described and bluetooth works.
Please note I didn't uninstall the custom kernel from before. I don't know if
this matters.

Hi Kai-Heng,
I'd love to try that out, however there's no installation instructions I can
see & google isn't being helpful.
Could you direct me to some install instructions?

Before sending my fix upstream, can you test latest linux-firmware?

Kai-Heng: thanks for the suggestion, bluetooth now switches on & I can
pair with devices.
Output of "dmesg | grep -i bluetooth" looks healthier too:
martin@martin-N15-17RD:~$ dmesg | grep -i bluetooth
[ 18.577708] Bluetooth: Core ver 2.22
[ 18.577724] Bluetooth: HCI device and connection
Hi Daniel & Kei-Heng, thanks for the suggestions.
rfkill doesn't do much
> martin@martin-N15-17RD:~$ rfkill unblock 0
> rfkill: invalid identifier: 0
I'll try the kernel you suggested next.
