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

If you exchange the two cards between the devices does the tablet with the non-working card start to function as expected? – Ramhound – 2020-01-13T17:01:23.750
Sadly I can't try since it would invalidate warranty – fat – 2020-01-13T18:25:15.543
2Go through the warranty claim process in that case. Without the ability to confirm if this is a hardware or software configuration problem, or provide us the required information to make that determination, this answer is next to impossible to answer. – Ramhound – 2020-01-13T18:30:10.327
Thanks for pointing that out, I thought Windows gave me a way of checking if some component was actually plugged in or something like that but seems like it's not the case. I'll answer my question once i manage to solve the issue – fat – 2020-01-14T07:01:48.967
