This happened to me, turns out the MB was overdriving the USB bus and burning out controlers.
Try them on a different PC and see if they work, if they dont, I bet you have the same issue.
Not sure of a fix for it, but a squadie is gonna fun a bios check for me to see it a setting is off.
If not I gotta get a new MB and all should be ok, if not, then I assume it is the Power Supply.
Good Luck
