hi, I am trying to change the irq settings because my Video Card and usb controller are both sharing the same irq number. I got into device manager and looked up the usb controller. I want to change the irq settings but everything is faded out I am using windows 2000 and I am logged in as administrator. how can I change the irq setting in that window? I tried changing them in bios but everytime I change the irq for the usb controller, the number for the video card gets changed to the same number as well! can anyone help? I appriciate it.
