I had the same problem when I built my new PC. None of my USB devices worked. I went into the Device Manager and selected each of the controllers under the Universal Serial Device controllers and asked it to look for updated software. I did this for ALL of the listed controllers. I found 4 out of 20 of them were outdated. Once I updated al of them I then rebooted and it fixed my problem. I hope this helps.

It seems your front USB cables are not good. Are they supplied by your motherboard package?
