Try this-

GO to Device Manager-

Select each USB Root Hub

Select the Power Management tab

Uncheck "Turn off to save Power"

Do this for each USB Root Hub

Select apply.

What does the Bios report your 12v, 5v and 3.3 volt?

Also. have you done Windows Update lately?

If not, there may be a driver update available.
