Go to device manager and double click on "universal serial bus controller". Then highlight what shows and click properties. Then click on driver files to see if they are installed. If not, click on update driver. You need to find these two files: 1. c:\windows\system32\drivers\usbhub.sys; 2. c:\windows\system\vmm32\ntkern.vxd. If you don't have these two files you can extract them from the installation disk (if you have Win 98) using system file checker (SFC). Go to start/run and type in SFC and click OK or hit enter. Then you need to click the radio button on "extract a single file..." Fill in the file you want and instruct it to install it in the appropriate directory as shown above. When you have both files properly in place you can click on update driver. You'll have to manually tell it where these files are located in the dialog box that will pop up when it cannot find the files. There is a usb.inf file that will do the install located in c:\windows\inf. If you type in that file Windows will do the install from "update driver" when you get the wizard. You will still have to tell Windows where these files are located. It will not look in system for them because they are supposed to be updated files. If the files are already in place the update feature will not work. On a shutdown/restart Windows should find them and install the software for them unless the problem is more serious. Have you booted into safe mode to check device manager to see if they show up? Subject: [PCBUILD] USB ports Can you help me, I somehow lost my usb ports. They are part of the motherboard.
