It's popping up in Ubuntu forums e.g.
https://askubuntu.com/questions/1448731/bluetooth-not-working-no-controller-available
| Reloading `btusb` module several times makes it working.
Any specific steps for this? I have not been able to get it to work.
Issue persists despite reboots incl. hard power off/on. This happened
suddenly.

(I believe the bleeding cutting edge 23.04.1 is the only available bunty
release with a 6 kernel line. Could be wrong.)
Note the workaround in the askubuntu question:

Title:
| Kernel 5.15 Regression | ' Bluetooth: hci0: command tx timeout '
Status in linux package in Ubuntu:
Confirmed
Bug description:
With the current daily-build of 'jammy 22.04' it is not possible to enable
Bluetooth with (some) Intel Bluetooth devices after reboot/warm boot.
With a Cold boot it is working.
My hardware: $ lsusb
Bus 001 Device 004: ID 8087:0a2a Intel Corp. Bluetooth wireless interface
This is because of a regression in Kernel 5.15 and was present in Fedora and
other Distributions as well.
https://bugzilla.redhat.com/show_bug.cgi?id=2027071
https://bugzilla.opensuse.org/show_bug.cgi?id=1193124
For example on Fedora35 my Bluetooth did not initialize correctly
after warm boot between versions 5.14.18 > 5.15.14.
After a cold boot it worked.
(Turned off the desktop PC and disconnected it from power for a few seconds.)
Kernel 5.15.15 changed that and since then everything went fine again.
