Hi!
I have been fighting with this HP 250 G7 laptop for weeks, with no luck.
It spors a combo wifi/bluetooth rtl8822ce
(https://linux-hardware.org/?id=pci:10ec-c822-103c-85f7&page=3#status)
Wireless works fine, but bluetooth is not detected, no hcix devices
comes up, and obviously bluetooth utilities (hciconfig, rfkill) do not work.
I have tested half a dozen of kernels (from 5.8.19 to 5.12.8 and some
patched alternatives), and alternative modules like
https://github.com/lwfinger/rtw88. A friend with the same laptop tried
to apply a patch (for archlinux)
I'm attaching the file "dmesg-hp-250-g7.txt", which contains the output
of a dmesg after booting a 5.10.0 kernel (backported to Debian 10) with
the lwfinger modules loaded, but the result is pretty the same with any
other kernel or module. I am also attaching the result of lsmod and lspci.
Am I missing something? Can I add some more debug info to help with a
diagnose?
Thanks in advance for any solution or clue.

Your dmesg and lsmod outputs do not show a BT driver loading. It is a separate
device from the wifi unit.
Please reply with the output of 'lsusb'.

Sorry, but I sent a mere lsusb without -v flag. Please, check the
attached verbose output.

Here you are:
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 0408:5365 Quanta Computer, Inc.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
(I even suspected there is not a working bluetooth chip, but it works
when I boot the preinstalled Windows 10)

The above output shows only 2 hubs and a camera (the Quanta device). I see no
mention of a BT device.
I think you failed to attach the 'lsusb -v' output, but the verbose output is
not needed.
