I have a Dell Latitude E7250 with

    Bus 001 Device 003: ID 8087:0a2a Intel Corp. Bluetooth wireless 
interface

and Bluetooth seems to work fine minus some Linux warnings [1] and a 
problem transferring greater than some bytes files with the Nokia N9 [2].

Linux 5.16-rc3, Dell Inc. Latitude E7250/0TVD2T, BIOS A19 01/23/2018:

```
