Let me preface this by saying that this specific dongle might be already broken
since even on Windows it works but disconnects after a while. Personally, I've
given up on those fake adapters and ended up buying a good one, but I'll share
my test results here just in case it helps someone else.
For me, with this latest patch (On Arch with kernel 6.1.1-arch1-1) the dongle
still doesn't work.
When I boot up with it connected, btmon gives it an empty index:
> New Index: 00:00:00:00:00:00 (Primary,USB,hci0)
dmesg outputs:
> [ 4.915236] Bluetooth: hci0: CSR: Setting up dongle with HCI ver=9

Curiously, if I disconnect it and reconnect it quickly, btmon does give it a
valid index:
> = New Index: 00:1A:7D:DA:71:10 (Primary,USB,hci0)
And Dmesg outputs the following (notice the two last messages are different):
> [ 79.189612] Bluetooth: hci0: CSR: Setting up dongle with HCI ver=9
> rev=3120; LMP ver=9 subver=22bb; manufacturer=10

This only happens if I connect it quickly after disconnecting, it I take a few
more seconds, btmon still gives it an empty Index.
Either way, the dongle doesn't work at all and doesn't even show up in Plasma,
even with a non-zero Index.
I hope this can be useful.
