Mein großer Rechner findet den TV und die Lautsprecher nicht.

dmesg | egrep -i bluetooth                                                                                                         ✔

Das Notebook findet es anstandslos.
Da fehlt aber die Zeile mit dem audit. Dafür ist eine Zeile mit usb 1-1-1 dabei.
Weiß wer Rat ?

Nachdem ich nun heraus gefunden habe das das Teil ziemlich verbugt ist habe ich mir einen ASUS BT500 Bluetooth Stick zugelegt.

Jetzt die Frage: Wie kann ich den Onboard Bluetooth Adapter am besten tot legen ?
Im Bios, was das einfachste wäre, geht es nicht.

Erstelle eine udev Regel in /etc/udev/rules.d/
