Bluetooth adapter resets on boot

I am trying to understand the behaviour of my bluetooth adapter on boot.

From what I see, there is some known issue and the system automatically resets the adapter to fix "command 0x0c24 tx timeout". Is there some kind of update to the firmware or else to fix this completely?

Re: Bluetooth adapter resets on boot

It has started to happen to me with 6.6.2 Different timeouts of hci0 commands that end up with a reset of the usb bluetooth adapter. Aso in my case after usb reset, bluetooth interface changes from hci0 to to hci1 breaking different scripts that detected the bluetooth usb adapter in hci0 during the boot.

Downgrading to 6.6.1 and no more bluetooth timeouts nor resets:

$ sudo dmesg | grep -i blue

EDIT: 6.6.3 still the same
