Look in device manager it is possible they are turned off/disabled. Right click on each item under "Universal Serial Bus Controllers". If disabled you will see enable, click on it and check each one. You will probably need to reboot if changes are made. If that is not the the issue drivers might need to be installed. If there is security software installed check it it might be blocking USB ports to keep nasty stuff from attacking your system when USB drives are plugged in. Good Luck.
