I don't think the device is broken since bluetooth + wi-fi is fully
functional and i also read on arch linux forum people get the same
message on tty with the same hardware. (AX200)

I suspect it is some vendor event other than MSFT that we are trying
to parse as MSFT, this normally can be ignored silently when not
understood, but I will check internally what we can do about it.

Hello,

First of all, my bluetooth adapter is;
04:00.0 Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a)

You've reached the Wi-Fi team here though - adding the BT list.

I see the following message everytime when i boot the pc on tty.

"Bluetooth: hci0: Malformed MSFT vendor event: 0x02"

But bluetooth works well. If it is not critical it shouldn't print on
tty, right?

That's generic from net/bluetooth/hci_event.c, not related to the device
(apart from the fact that the device might be broken if it's sending
this?)
