T420 driver Windows 8.1

2016-11-01, 14:40 PM

I have T420 Laptop (ThinkPad - Type 4178A3) ond Windows 8.1 64bit.

 

In my windows device manager I have one device without driver. 

All windows updates (including optional) are installed.

I also checked my laptop via Lenovo System update tool in support page (Drivers & Software tab) with a message "No drivers are required to update for your machine".

 

The device with missing driver is in category Other devices / PCI Serial port.

The location is : PCI bus 0, device 22, function 3

Details:

harware Ids:

  • PCI\VEN_8086&DEV_1C3D&SUBSYS_21CE17AA&REV_04
  • PCI\VEN_8086&DEV_1C3D&SUBSYS_21CE17AA
  • PCI\VEN_8086&DEV_1C3D&CC_070002
  • PCI\VEN_8086&DEV_1C3D&CC_0700

 

Could anyone help which driver I need?

 

Thanks in advance
