Manjaro Gnome - Can't find bluetooth devices

Hello,

I’m using a Cambridge Silicon Radio Bluetooth Dongle (HCI mode) on my desktop, but it can’t find any bluetooth devices: neither bluetooth settings nor ‘bt-device -l’ seem to work.

Removing manjaro-firwmare and installing bcm43142a0-firmware didn’t work.

I’ve got the following bluetooth related packages

blueman 2.1.4-1
bluez 5.55-1
bluez-libs 5.55-1
bluez-tools 0.2.0-5
bluez-utils-compat 5.55-1
gnome-bluetooth 3.34.3-1
pulseaudio-bluetooth

Any help is appreciated.

Thank you.

Sorry, I have nothing to offer other than to say that I apparently have the very same adapter (different Revision: “88.91”, but same vendor and device ids) and it works just normal. And I did nothing special, neither installing nor configuring something else.

What about bluetoothctl? Doesn’t scan and list there either?

Thank you for the reply.

‘scan on’ returns nothing.

Very weird. Do you have it connected directly to your motherboards rear USBs, front hub in the case, an external USB hub? USB2 or USB3 port?

Did you tried with different kernels?

I’ve tried front and rear USBs, both USB2 and USB3, with no success.

I’ve not tried different kernels. Do you recommend any?

I use the same that you use right now, but in this long thread about the huge list of problems with this adapter, someone claims it had more luck with 5.4, so the current LTS one?

Ok, with LTS 5.4.89-1 and the dongle connected in the rear USB3 port, I can find and pair my headset.

But I can’t connect it.

Damn! So close… Did you try with anything other than that particular headset?

I have another JBL headset, no success though.

Also, I’ve tried using this dongle in Ubuntu 20 and Windows10 without success. I don’t know whether is the problem, the dongle or my motherboard.
