i'm not sure how you would check, except for maybe via the device manager.

but here's an example of what you would need to do to install such a thing. my motherboard at home has the intel 856pe chipset. so, i went to intel.com > chipsets > 865 family, chose my OS, and it gave me a list of downloads. so i pulled the right one and installed. i think this also allowed me to install USB 2.0 drivers, so it may help you.

do you know what motherboard you have? maybe i can step you in the right direction. you may also be able to find this on the CD, but on the net would obviously be more recent.

however, it just occured to me that this is a usb controller on a pci card, not a motherboard, so this may in fact do nothing. but it's worth a shot.
