My T420s is not recognizing my fully functional USB key that I tested on other computers.
Given what I've seen in Device Manager (attachment), it appears to be a USB Mass Storage Device driver related issue so could someone tell me which driver to reinstall?
Drivers and software - ThinkPad T420, T420i, T420s, T420si, T520, T520i and W520
Thanks a lot then!

What error does it say when you right-click the USB Mass Storage Device in Device Manager and go to Properties?
-
"Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"
Thanks again. -
Tsunade_Hime such bacon. wow
Have you tried uninstalling the USB controller and reinstalling it? Perhaps something got corrupt.

Actually I tried that but then I had 2 consecutive BSODs after which System Restore failed as well. So I restored everything back to factory state using the recovery media.
Thanks for helping though.
