If you have already run the Troubleshooting Wizard, you might want to check the hardware

documentation for more information about diagnosing the problem.

Method I
I would suggest you to run the hot fix and see if that helps.
If your high-speed USB 2.0 ports don't work, you might not have the correct driver installed for the ports in your computer, or the ports might be defective. If you are using an external USB hub plugged into your computer, this might also be defective or lack the proper drivers. Check Device Manager to see if your USB ports or hubs are working properly.

1.       Open Device Manager by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clicking Device Manager.‌  If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

2.       Double-click Universal Serial Bus controllers and check to see if all your USB ports, hubs, and controllers are functioning correctly. Any devices not functioning will have a yellow exclamation mark in front of them.

3.       If Device Manager shows any USB ports, hubs, or controllers are not functioning, check for updated drivers. For more information, see Update a driver for hardware that isn't working properly.
