Ok, this is interesting. I just downgraded to bionic (18.04) and now the
dongle is working! So something went wrong somewhere along the way but
the H/W is definitely good.

Ok, I tried again but changed the command with the version above to:
make SUBLEVEL=0 EXTRAVERSION=-46-generic modules_prepare
Now I get in dmesg:
[ 7851.540982] usb 10-1: new full-speed USB device number 4 using xhci_hcd
[ 7851.788016] usb 10-1: New USB device found, idVendor=0a12,
Here are the steps I followed (all on Eoan):
sudo apt install kernel-package linux-source flex bison libssl-dev libelf-dev
tar xf /usr/src/linux-source-5.3.0.tar.bz2
cd linux-source-5.3.0
make mrproper
cp /usr/lib/modules/5.3.0-46-generic/build/{.config,Module.symvers} .
make oldconfig
patch -p1

It seems this dongle currently takes an additional patch to enable. Does it
work for you?

Gave it another try with linux-image-unsigned-5.7.0-999-generic on Eoan,
same behaviour.

Sorry for the delay. I have just installed 20.04 to try but the
behaviour is the same.
Dmesg log when I plug in the dongle:
[ 230.119651] usb 10-1: new full-speed USB device number 3 using xhci_hcd
[ 230.375357] usb 10-1: New USB device found, idVendor=0a12, idProduct=0001,

Sounds like this might be a kernel bug, or a hardware problem. I am
skeptical of CSR Bluetooth dongles since they seem to be consistently
unreliable, at least on Linux.
Please try a newer (or older) kernel version and tell us if that makes
any difference:
