Win 7 and USB 3 Driver

I need help locating the USB 3 driver that I am using in Win 7 64 bit.
I am trying to create a System Restore disk for Symantec System Recovery so that in the event my hard drive crashes I can copy back my most recent backup. The problem I am having is my backups are on a 2 TB USB 3 portable hard drive and I need to find the driver for USB 3 so that it can loaded on to the Restore Disk.
