Hi Gobias,
my friend, referred to in my message of last Monday, has in the meantime bought the Fenvi T919 card.
Since it is an OOB card I thought that it was enough just to mount it and instead I was not able in any way to activate the Bluetooth on Monterey.
I tried to install the various kext, to make changes but nothing.
On Monterey wifi works bluetooth, however, there is no way to activate it.
On Windows 11 everything works both BT and Wifi, I also updated the drivers from the Fenvi site.
As a test I also swapped the new Fenvi card with my old one, present on my Msi Z690 and fully functional, but nothing to do.
The connection to the MB on the z490 I did it to the pciex1_3 slot and inserted the connection to usb trying both on usb_e12 and usb_e34.
I have now noticed that the UART and not USB connection appears on the system / bluetooth report.
I ask you, and anyone on the forum, how I can solve.
