Solution not working on 5.13 kernel
Closed this issue · 5 comments
Hello! Can you help me out? I tried to reproduce your solution from your commits using kernel 5.13 (ubuntu 20.04) but bluetooth still doesn`t work. Behavior is that bluetooth shows up on the system, but never finds any devices while scanning. I tried many different bluetooth devices which are working.

Well, this driver is just for RTL8852BE while your device is RTL8111E, but I think the principles are the same.
please print the result via lsusb and sudo dmesg | grep -i blue
By the way, It is 10+ years old since RTL8111E released...
I think
the first step is to get btusb to recognize your device,
and the second step is to get btrtl to recognize your hci_ver, hci_rev, lmp_ver and lmp_subverand load the firmware information correctly at the same time.
Let me tell you that this is odd behavior. I have a windows dual boot on this machine (redmibook pro 15 ryzen edition 2021) and it shows up correctly as 8852be device. For some reason, ubuntu 20.04 isn`t able to even recognize this board.
Solution was to update to latest (ubuntu 22.04 with kernel 5.15) and use your repository. Now it works.
