Are you able get into BIOS? See if the USB ports (and camera for that matter) are disabled therein.

Should not have happened unless you specifically went in and did so. I.e., to prevent USB flashdrives from being able to boot the system.

However there are various diagnostic tests you can run from BIOS.

Reference the L520 Maintenance Manual - hopefully the following link is the correct manual for your L520:

Are you aware of any changes to your Thinkpad?

Some new install, some update....?

Any problems or error codes/messages being displayed?

Go to Windows Settings, Devices, USB. Click on the "Notfiy me" button. Restart and see if you receive any notifications regarding USB connection issues.

Try reinstalling the drivers anyway.

Ralston, thank you very much for your reply,
I'll check the USB inputs, and truth,
the manual will help me a lot.
Thank you very much, after the tests, I'll post a reply.
