USB 2.0 Drivers
Preferred Driver Loading Order for Intel Chipset Based Motherboards:
Checking Driver Installation So you think you might have incorrectly installed the drivers? There are a number of ways to check your system for incorrect installation. First of all, you can check registry settings to see if the chipset driver was installed on the system. By launching the registry editor application, you can view a value that is designated to flag a successfully installed chipset driver. Using the start menu, select "Run…" and enter "regedit" to launch the application. Expand the directory structure as seen in figure 1. Select HKey_Local_Machine/SOFTWARE/INTEL/InfInst and view "Install" to see if the data reads "success". If this registry setting does not read success or you do not have these registry directories, then the chipset driver was never successfully installed. ![]() Figure 1: Registry information indicating chipset driver installation Even if the chipset driver was installed, if it isn't installed in the correct order it will not enable all chipset features. This can be checked by using the freeware WCPUID* tool. This tool is also available at a number of other websites and can be searched for by a number of common search engines. Using this tool, you can check chipset registry information. Figure 2 is a cropped view of the AGP chipset information that can be viewed using WCPUID. Note the gray values under both the status and command columns that indicate properties that are not established. Under this incorrect driver build order, the OS does not know how to use the graphics features. ![]() Figure 2: WCPUID view of the disabled AGP bridge Figure 3 displays the same section of WCPUID as in figure 2 only figure 3 displays the result if you have correctly installed the chipset driver. Although many other features of the chipset can be disabled when the chipset driver is installed incorrectly, the AGP bridge information is one indicator that can easily be checked. ![]() Figure 3: WCPUID view of the correctly enabled AGP bridge
