Call the main system menu by clicking the "Start" button and go to the "Run" dialog. Type devmgmt.msc in the "Open" line and confirm launching the Device Manager utility by clicking OK. Select the computer name in the list of the dialog box that opens and select the "Update hardware configuration" command from the menu of possible actions.
Step 2
Reboot the system and check if the USB ports are working.

Repeat the above steps to launch the Device Manager utility and open the "Universal Serial Bus Controllers" link in the dialog box that opens. Call the context menu of the first controller by clicking the right mouse button and select the "Delete" command. Remove all other controllers in sequence and reboot the system again. This action will automatically update the configuration and reinstall the remote controllers.
