ThinkPad T410 device manager unknown items

Question

Having done a clean install of 64bit windows 7 Professional, I am left with 3 unknown devices under 'Other devices': 'Base system device', 'PN533' which I think refers to a NFC controller[my Card reader seems to be working fine] and a 'Unknown device', which I suppose could be almost anything. Can anybody out there help me? No reference to PN533 in Lenovo T410 driver page.

Thanks for considering this issue.
I can't say it was there out of the box, but I do know it was still there after some Windows updates and Lenovo updates. However, the inactive devices finally started working after I found in the Lenovo Metro applications that there were drivers updates available. I installed dependencypackage.exe and settingsdependencyp.exe and I think that is what solved the issue. Finding these updates was not straightforward though, as they were not advised in the Lenovo Solution Center, only in some Metro applications.
I am not sure the devices are working properly though, as I can't pair with my smartphone using NFC (though NFC does appear in the wireless settings), the Map application in Metro is not finding my location acurately which makes me think it only uses my internet connection and not the GPS (though the GPS appears in the wireless settings). As for the WWAN, I don't know why, but the Lenovo Mobile Access Metro application stopped working. I only get the splashscreen then it crashes without any error message. I uninstalled/reinstalled but same behavior. WWAN appears with a "Macheen" network in my connection options when I click on the connection icon in the systray, but it won't work: "connection impossible". Don't know if it is because the device is not working properly, or because the Mobile Access applicasion is not working properly.
The two "unknown" devices are still there, still unknown. I don't know what they actually are.
