This one seems like the same unregistered USB VID issue as in #1955351.
A patch was submitted by Helmut Grohne and accepted. The firmware seems
to also appear now on the linux-firmware repo.
Someone should submit this patch to sta...@vger.kernel.org so that it can get
backported.

Never mind it works now, the reason was that I did download the firmware
but didn't properly apply the patches if you can call them that to btusb.ko.
Thank you for your patience and for providing quick solution.

What's the output of the following?
sudo modprobe -r btusb
sudo modprobe btusb
sha256sum /lib/modules/`uname -r`/kernel/drivers/bluetooth/btusb.ko
xxd /lib/modules/`uname -r`/kernel/drivers/bluetooth/btusb.ko | grep "ca04 0540"
xxd /lib/modules/`uname -r`/kernel/drivers/bluetooth/btusb.ko | grep
Sorry tried what you suggested but didn't work also rebooted just to
make sure. Disconnected and connected it just to show it got detected
dmesg | tail

The problem is that the USB ID for this chip is not in the btusb module.
Many people report the same problem elsewhere, though it seems most want
to try and use a strange module from a random BT dongle manufacturers
website, which is just crazy. The proper thing to do is to add the USB
ID to
apport information
** Tags added: apport-collected focal
** Description changed:

The device is recognized, hciconfig -a shows a device, no errors at all.
It can scan do whatever. The only thing it doesn't do is find anything.
