I got a strange problem whit my usb ports. Every time i plug in a new device all usb ports stops working. I have reinsall drivers in safe mode. Nothing works, I have win7 ulti.
Go to the manufacturer of your motherboard's site and download the latest Chip Set drivers and install them. You may have gotten a corrupted USB Hub driver etc. If their USB drivers are in a separate file then down load that one also.
Reboot the machine and see if the USB ports work as they should.

I used a third party (DriverMax) to find drivers for my usb hubs. It was the only place that I could find them. You might try a third party to see if that will do the trick.
