Did your computer come with a system restore CD or a system resouce CD? These would have had the drivers needed.
For the SM BUS CONTROLLER you will need to install the motherboard chipset drivers.
For the PCI MODEM you will need either the Motorola MSP2900 modem drivers or the Smartlink MSP2900-W modem drivers.
For the PCI DEVICE, well that's a toss up. It could be your sound or your ethernet.
By installing the chipset drivers, it should help with Universal Serial Bus (USB) Controller.
I am kinda suprised that your graphics isn't giving you problems.
You can download all the drivers here.
