T400 Cannot find PCI Simple Communications Driver and PCI Serial Port Driver in Device Manager

2015-08-22, 19:48 PM

I am restoring a T400 741722U, putting Windows 10 on it, and I cannot find one of the drivers. Going into Properties of the "PCI Simple Communications Device Manager", I find that the vendor is "8086" (Intel) and the device is "2A44". I find nothing on the Lenovo site. The laptop seems to be working properly (except for the speakers, which must be disconnected as the audio jack does work) and all other drivers have been installed and updated. 

 

Can anybody help here? Thanks.

Good day.

 

In my experience the Intel Active Management Technology and/or Management Engine packages supply drivers for these.

 

Checking here: http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t400
under the Chipset section, I don't see packages for Windows 10, though.

 

Regards.

Yes, I had previously tried the Windows 8 driver, but it does not work.

I just got an email asking if I had received the answer I needed.

 

No, i did not. I still have not found a driver for this PCI Simple Communications device (for Windows 10).

 

I'm still not sure what the device is for? 

 

Perhaps somebody else with a T400 has solved this problem. I'm sure many T400s have already been upgraded to Windows 10.

Good day.

 

The email was just an automated feature of the forums.

 

Again, the device is a component of Intel's Active Management Technology/Management Engine Interface.

You can see a description of AMT here: http://www.intel.com/content/www/us/en/architecture-and-technology/intel-active-management-technology.html

 

If your machine is not part of a corporate environment, being remotely managed by an IT department, you can safely ignore the device, IMHO.

 

Regards.

In the same boat, but I don't see any user impact on this while using Windows 10. I am still waiting on the Fingerprint driver for Windows 10, which is more of an immediate PiTA
