8852BE Bluetooth not working after BIOS update
kovadam69 opened this issue · comments
Hi
Connected to the other issue on the wifi driver I managed to get further, at least now the BT driver is loaded and prints some info into dmesg. I discovered, that the BT product ID has been changed to b85c which was NOT present in the btusb.c. I now added it and now the lines starting with ****** appeared, so the btrtl.ko is loaded now, but then it fails.

And because of this failure the USB ports 1-3 are restarted continuously.
Please tell me if I should try diverse things or provide additional information.
this is my lspci output

Strange, that the "output of usb_match_id" is different with the two kernels, and the "driver_info" is also different.
one thing let me struggle,
you wrote 8852BE - this is a driver for chip/device on pcie-bus,
now you will use BTusb driver - this is for chips on usb-bus, not on pci,
you have added b85c to btrtl.ko, that can or should work but not in btusb.ko....
i think the IC which have the 8852be includes also the BT-part as coexisted chip -
but i am unsafe now
you have to add the ID b85c on btrtl,... not btusb ?
The RTW8852BE is a package that contains a wifi part on the PCI bus, and a BT part that is on the USB bus. The Vendor Number for the two parts are different; however, the Device Number might be the same.
Updating the BIOS would not have changed either the PCI Id for the wifi part, nor the USB Id for the BT part. Please post the output of lsusb.
The way that the BT driver works is that btusb does ALL the device recognition, and then uses one of the parameters to determine which vendor-specific part to call. Your log output above shows it working just as it should. Drivers btusb/btrtl run the BT part.
