T430s not recognizing USB 3.0 (SS) - Windows 7

Lenovo T430S

OS: Windows 7 Pro


The yellow USB works perfectly


The two blue USB's, both with "SS" do not work.

*When plugging in a mouse nothing happens.  The mouse does not have power and the OS does not recognize. 

*When plugging in a thumb-drive the red light on the thumb drive illumintes then goes out.  Nothing shows as recognized with the OS. 


Device manager has all hardware with drivers.  

In Device Manager, under Under USB Controlers, one is listed as, "Unknown Device."  When I try to update the drive it says its "Intel USB 3.0 Root Hub"


I downloaded USB drivers for Lenovo T430s from

*Intel(R) USB 3.0 eXtensible Host Controller

I also tried uninstalling all USB drivers and rebooted and also nothing has changed. 

BIOS has USB settings all turned on (some were auto originally).

Re: T430s not recognizing USB 3.0 (SS) - Windows 7

Seems this stumped most everyone.


Fortunalty I had another HDD and as I was searching for the right drivers to get WiFi to work the USB 3.0 drives started working.  When I compared the Device Manager I noticed that "Intel(R) USB 3.0 Root Hub" was present using the HDD where the USB 3.0 worked and missing from the other HDD.


I downloaded the drivers from Intel (rather than from Lenovo as I did previously) and I was able to update drivers (rather than running a Setup.exe)


As an aside, both HDD's had "Intel(R) USB 3.0 eXtensible Host Controller" installed prior to the fix so some correct Intel USB 3.0 drivers loaded, but but not all.
