I need a 2.0 USB port so I installed the driver that came with my Gigabyte GA-7VRX/GA-7VRXP motherboard. The board has 4 other USB ports that I use for my mouse, printer, etc. The driver does not have the Microsoft approval, but I installed it anyway. Now none of my USB ports work. I restored my Windows XP to an earlier date before the new driver insatllation and the ports still didn't work. The Device manager says that the 4 USB ports are working. I even uninstalled them and then after restarting the computer they were once again found and MS drivers installed. I then installed the XP SP-2 upgrade. That didn't help. My mouse, printer and scanner can not connect via the USB ports. What can I do to fix the problem. I did the printer troubleshooting exersize and did not find the solution. I can not even print from a command prompt or from win word. Thanks for your help.
