I have two Windows 10 (1803) tablet pcs equipped with a PCI-Express NFC reader. In the first one, NFC works like a charm, the second sadly doesn't.
In the second device, when I open the Device manager there's not a single "Proximity Device" in the list. The funny thing is that when i bring any nfc tag close to the reader, it makes a sound, confirming that the hardware reader is alive.
When I try to install its drivers (recommended by the tablet's vendor) the installer crashes with a "No such device" Error.
Adding a legacy device from the device manager seems to have no effect either, since it will just create a dummy proximity device that cannot start (Error code 10). To get to this last state, I tried many different drivers available online.
As a desperate act, i copied every nxp* driver from the other identical tablet. It won't work either.
How can I actually debug this error? If it is a hardware related issue I have to prove it
