Public bug reported:
I have a knock off CSR bluetooth adapter version 5 which does not work
with Kubuntu 21.10, kernel 5.13.0-22.
The bluetooth dongle seems to register:
ethan1@ethanubuntu:~$ rfkill list
enter code here
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
Bluetooth service appears to be running:
● bluetooth.service - Bluetooth service
Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset:
enabled)
Active: active (running) since Fri 2021-12-31 06:57:52 AWST; 4min 13s ago
Docs: man:bluetoothd(8)
Main PID: 1752 (bluetoothd)
Status: "Running"
Tasks: 1 (limit: 9317)
Memory: 1.6M
CPU: 17ms
CGroup: /system.slice/bluetooth.service
└─1752 /usr/lib/bluetooth/bluetoothd
Yet running:
ethan@ethanubuntu:~$ sudo hcitool dev
Devices:
Says the dongle is not found as no devices are found.
Same with bluetoothctl:
ethan@ethanubuntu:~$ bluetoothctl
Agent registered
[bluetooth]# show
No default controller available
