Standard Enhanced PCI to USB Host Controller Missing

All of my USB ports began running very slow. I only noticed this attempting
to back up a large file. Upon investigating I discovered my Standard Enhanced
PCI to USB Host Controller was missing from my Device Manager.

I have run Microsoft Update several times, I have uninstalled all the USB
devices and rebooted to reinstall the USB devices but the missing Host
Controller does not return.

I tried system restore with out any success. I can't reinstall the operating
system because I can't back up my drive with the USB ports running so slow.

What do I do now? I'm not that Tech Savy so you have to explain in simple
step by step terms please.
