The hardware itself is functional= if I boot on an older kernel, and the actual Bluetooth software stack seems fu= lly functional, but on 7.0.7 any attempt to connect an already paired device fa= ils, with bluetoothctl reporting "No default controller available". I have attached the output of "sudo dmesg | grep Bluetooth" from a boot on 7.0.7. --=20 You may reply to this email to add a comment.
