Can anyone provide some clarification on the following issue, Peter
I=E2=80=99m trying to play around with the NFC module in the X240, but it s=
hard to find information on that. I=E2=80=99m not even sure which module t=
is. Lenovo=E2=80=99s FRU list suggests it might be a =E2=80=9CFoxconn 2079=
2S=E2=80=9D, but then
the Windows driver download page mentions Broadcom. How does this
fit together? Is it a Broadcom chip that Foxconn soldered on a PCB and
made into a complete NFC module?
Then again, there=E2=80=99re mentions in the internet that the previous Thi=
generation used the NXP NP533 module, for which there is a driver in the
3.13 linux kernel that I could not get working (neither lsnfc from
nfcutils nor nfctool from the neard package would show any NFC
devices). I also tried the PN544 driver without luck.
Outputs of lspci and lsusb aren=E2=80=99t very helpful to me, there=E2=80=
there that I=E2=80=99d recognize as NFC. Strangely the Hardware Maintenance
Manual doesn=E2=80=99t mention NFC at all.
I was starting to think I might not even have an NFC module, but the
invoice clearly mentions it and there=E2=80=99s also an NFC setting in the =
(which is set to Enabled).
Any suggestions? What make of NFC module does Lenovo build into the
X240 (and the othe Haswell Thinkpads)? Are there any Linux drivers
