Public bug reported:
Whenever I boot, the following error message always appears in dmesg,
suggesting an issue with Bluetooth, likely with initializing the
bluetooth adapter:
[ 54.902144] Bluetooth: hci0: Opcode 0x0c03 failed: -16
When I try to enable bluetooth in System Settings, nothing happens. The
enable button continues to show, even after clicking it multiple times.
The Bluetooth widget in the system tray allows me to 'add devices', but
the dialogue shows no devices, even though I have bluetooth devices
active and ready to pair.

When I internet search for chip ID 13d3:3602, I find a couple pages that
refer to it as the Mediatek MT7925 card. E.g.:
https://github.com/bluez/bluez/issues/995
Conclusion: The manufacturer is MediaTek; the vendor is IMC Networks;
the product name is Wireless_Device and the card goes by the name
Mediatek MT7925.
I've looked online for linux drivers for MT7925 and thought about
putting those drivers on my system in the directory
/lib/firmware/mediatek/mt7925 . However, the drivers already are in
that directory. So the system already has the firmware for this device.
The problem is that either linux itself or some related software such as
bluez is not initializing the device. This strikes me as an unintended
bug.
I have seen discussion online that the MT7925 card works starting with
kernel 6.11.5, on another Debian OS (nix). Kubuntu 24.04, however, is
on kernel 6.8.0. I like the stability of 24.04 and have put a lot of
time into setting up hibernation and software. I hope a fix can be made
available for my bluetooth.
What I expected to happen: Bluetooth can be enabled, can see devices,
can pair with devices, and can deliver audio.
What happened instead: Bluetooth cannot be enabled, so it cannot see
devices, pair with them, or deliver audio.
