[HELP] Dell Latitude 3450 DW1820A BT not recognise on ioreg


Recommended Posts


The problem still persist, I still cannot see any BT under USB port.

For additional information, BT on windows 10 is detected under USB 2.0 port.

But it seems, in macOS it cannot appear, I am not really sure why.

I had done several method to enable USB port on my hack, but still failed.


Do you have any idea? Thanks
