I bought a USB Bluetooth dongle for my manjaro computer but unfortunately, this won’t be recognized when I plug it in.
Can anyone give me some advice, please?
Should I buy a new one that is compatible with manjaro?
how do you know?
how do you check whether it is recognized?
When I plug it in and use the Blueman I see no devices.
Let me know if I’m wrong or I can use another method to make sure
You are a long time member - and should know how to retrieve and provide information.
anyway
apart from info about your hardware
inxi -Fazy
preferably with the thing plugged in
you could use:
journalctl -f
in a terminal
and watch the output as you plug in
and disconnect
your device
you can do a similar thing with:
sudo dmesg -w
in a terminal
both commands will show you
in slightly different format
what the system sees when you plug in and remove the device
The most obvious thing to check (which I didn’t even think of until now) is:
is the bluetooth service started and running?
It might not be - because there was no bluetooth device when you installed the system and therefore no reason to configure the service.
The majority of bluetooth dongles works with Linux. Long time ago - years - I bought a cheap Deltaco bluétooth dongle - as I recall the price was around €8.
Check if it is recognized by listing USB devices

Copy/paste the text from the terminal window into a reply - select the text and click the </> in the comment toolbar and click the reply button.
Example from my system with the Deltaco bt dongle

I’ve got this one:

But still cannot use it on Blueman

Maybe here is the problem:
sudo dmesg -w
[ 1390.441797] Bluetooth: hci0: CSR: Failed to suspend the device for our Barrot 8041a02 receive-issue workaround
… because my suggestion to check for it might have been overlooked:
is the service active?
systemctl status bluetooth.service
Yes, active and running
But still can’t use it.
It has the same device id as mine - and I have no issues connecting.
Albeit not blueman but bluedevil on KDE - you may need to do some low level troubleshooting
Check if you have bluez-utils package installed - otherwise install it
which bluetoothctl
Execute the command bluetoothctl which will open a bluetooth controller environment
list
Ensure the controller is powered
power on
Then scan for devices
scan on
Then stop scanning when you have seen it working
scan off
When I use list command on bluetoothctlenvironment I get nothing.
Also after using power on I get an error: No default controller available
And same error for scan on command
Then you have other issues
