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'.
