usb 2 works erratically

[obxeye]

have ga-990fxa-ud5 with amd fx-8150 running win7 pro 64 bit.  about 2 months ago usb mouse and keyboard quit working. a power reset and they would work again for a few days.  i thought it was my old logitech wireless usb mouse and keyboard so got a new one.  same problem. i have also discovered that when this happens all usb 2 ports quit working and not only for mouse and keyboard but any other device i plug in.  i suspected a win update as the cause but uninstall of last few months has made no difference.  also have cleaned out hidden and ghost usb drivers in device manager using http://www.sevenforums.com/tutorials/77614-device-manager-hidden-devices.html.  any help much appreciated.

look for KB2862330 update and uninstall it was a usb driver update that has caused all kind of issues.
