Several years ago, I built a computer with the H87M-ITX motherboard with the Intel i5-4670K CPU. Recently the USB ports mostly stopped working. I think it's a hardware problem because I have the machine dual booting in Windows and Linux and the USB devices don't work in either OS. But the keyboard and mouse, which are also USB devices, still work. I've tried all of the USB ports and they all show the same behavior (front USB2 and USB3, and rear USB2 and USB3). I'm using a graphics card so I can't plug in a PCI-Express USB card, since there is only one pcie slot. I have also tried to re-flash the BIOS but have not been successful, since it can't read the USB ports and the Internet Flash option in the BIOS seems to not work either. I've tried plugging in USB drives and a USB video camera into the machine without success. The same devices work fine in other machines.
Is there anything that might cause all of the USB ports to stop working at once, and is there any hope for fixing this machine? Buying a new motherboard for this old of a machine is prohibitively expense, just as expensive as buying a new modern motherboard. This machine is primarily for the kids to do school work so I'm not interested in spending a lot of money to fix it.
