That means that the ports could support USB 2.0 but were currently running at 1.1. Note that as the USB 2.0 was nearing release, Intel was shipping motherboards that had USB 2.0-ready host controllers. A USB 1.1 port can support USB 2.0 but will only deliver speeds up to what 1.1 was capable of. USB is a standard that continues to evolve and is backward-compatible. The Intel driver is more sophisticated in that it is designed specifically for this USB host controller implementation. Generic drivers adhere to the basic functionality of the USB standard.
So, why use this official Intel driver rather than a generic implementation. Windows can usually install a generic driver that will provide basic performance for you. It is not a generic driver that you should use just because you have an Intel CPU or any Intel motherboard. Note that this driver is designed specifically for Intel motherboards and certain boards in particular.
There is both a 32-bit and 64-bit version as well as versions of this package designed for versions of the Windows operating system that are older and newer than Windows 7. The Intel USB 2.0 Driver for Windows 7 is an official driver published by Intel for Windows 7 devices. This is the official Intel driver for the USB 2.0 Enhanced Host Controller.
