The Intel Chipset Software Installation Utility installs special Windows INF files. These INF files inform the operating system how to properly configure the chipset for specific functionality, such as USB, Core PCI, and ISAPNP services. Now to the confusing part - these are not the drivers for AGP or USB. The INF files allow the chipset and Windows to work with the drivers. In other words, you need the INF files, plus you will need to install the drivers separately (usually after restarting your computer). Intel give the following important advice: “Do not download this utility if your hardware manufacturer is recommending it to correct ‘usb driver’ issue – it will not correct your issue.”
Here is also a common problem and solution that people face after installing the INF update:
Problem: after rebooting, Windows cannot find UHCD.SYS, USBD.SYS or USBHUB.SYS files. Files appear to be missing or corrupted.Solution: click the 'Browse' button in the dialog box where this error occurs and locate the C:WindowsSystem32drivers directory and click on the 'OK' button (if Windows is installed on another drive or location, you should change the location accordingly, eg if it is on the D drive then use D:WindowsSystem32drivers). The system should be able to locate this file in this directory and continue checking for the new devices. Also try the driver disks that came with your hardware.
