On your Windows* device manager, expand the Universal Serial Bus controller option and then proceed to uninstall every single USB device by right clicking on them and selecting the uninstall option, then reboot your system and let Windows* install the USB devices by itself and then test your USB ports.
2. Take the system out of the chassis in a non-conductive surface and disconnect the front panel USB to avoid any short. Please follow the integration guide in the following link:
3. Remove any non-essential components from the board that might cause a conflict, for instance optical drives and external cards such as NICs, Sound cards, etc.
4. If the problem persists, clear the CMOS by removing the battery and power supply for about 45 minutes and then connect them again and check the behavior.
5. Finally back your information and then try a clean installation of your operating system following the critical driver installation order. The driver installation order is one of the most crucial issues when talking about overall platform performance. This is especially true for Intel(R) chipsets. The most critical step in the installation order is to install the Intel(R) Chipset Software Installation Utility first before all other drivers. The correct driver installation order is as follows:
a) Fresh Operating System Installation
b) Latest Service Pack or Patch
c) Intel(R) Chipset Software Installation Utility (INF Utility)
d) Rest of the drivers
