Every time I plug a usb mouse or keyboard into the cpu it goes through a hardware wizard to install the device. If I switch the mouse or keyboard out (due to the desktop is moved from location to location) It goes through the hardware wizard to install the device again. The keyboard or mouse is the same make and model. How can I install the drivers just once and not go through this every time? This is the only model of cpu that does this. All the others install the device automatic without opening the hardware wizard. Any ideas?
