This morning two of my USB ports quit quit working. Looking at the back of the unit, they are the two left most ports which I am assuming are the 3.0 ports. I have uninstalled all the drivers twice, both times on restart they automatically reinstalled. I am running windows 8.1 64 bit. Below is an immage of what I am seeing in the device manager. Any thoughts or suggestions on what to try next?

Not sure why the ports would suddenly stop working. You can try removing the ports in Device Manager and restarting the system to let Windows detect them again. Your best option may be to completely restore the system, to see if they work on a clean OEM load of Windows. If they don't, you would need repair to fix the ports.

I restored the system to a previous save point and it fixed the problem. I think the issue was caused by an app I installed for my new Jawbone speaker.
