The card is ok. It works on the i9 via a USB to microSD ok.
No card is detected though the reader seems to be ok at the device manager.
I have tried removing the driver and allowing windows to download the driver. But still KO.
No idea on how to proceed. The important point here is that it worked when I received it. Since then I have not installed any SW. Only automatic windows updates.
That is why I think donething is wrong with the driver after a windows update.
