PLEASE HELP - Downgrading from Windows Vista to Windows XP with a Presario (SR5152NX)

I'm currently up and running on my Compaq Presario SR5152NX, and i must say it is running like a champ, but i have only one problem, i can't find this "PCI Input Device" anywhere. I can't even figure what it is for. :confused The system seems to be running everything, but i still have a driver that needs to be installed, can someone please help me out with this situation???

A mystery PCI Input device is usually one of three things: a sound card, a modem, or a game port/MIDI port. It may also be a system level device controlled by the chipset. I'd recommend downloading and running Unknown Devices; a very helpful tool to find out the gritty details of these mystery listings in the device manager.
