My wife bought this laptop a while ago and Bluetooth has never worked on it with Kubuntu. The Bluetooth Manager appears to be working, however never detects bluetooth devices. The laptop also cannot be detected from other devices. I have already conducted the following fault finding steps which did not rectify the fault:
Ubuntu Bluetooth Troubleshooting Guide
lsmod | grep bluetooth

Here I have tried to connect multiple devices and none are detected:
bluetoothctl

[bluetooth]# power on
[bluetooth]# Changing power on succeeded
[bluetooth]# scan on
[bluetooth]# SetDiscoveryFilter success

I also followed the fault finding in this post here which didn't fix the fault either: Bluetooth not finding any devices ( Ubuntu 18.04 )
Blueman reacts similar to the default bluetooth manager, it shows data being sent and received but no devices show up on the list.
Results for [lsusb; sudo dmesg |egrep -i 'blue|firm'] command are as follows:

Any help would be greatly appreciated.
Cheers.
