I purchased a ASUS P5W DH Deluxe Motherboard a couple weeks ago and have been have not been able to get the USB ports to perform at there full speed. Windows XP says that I have no "Hi-Speed USB host controllers" installed on my computer. Also with the driver cd for the motherboard, when I clicked on "install USB 2.0 drivers" a text document came up saying that if I was using windows xp or later I did not need to install the drivers (I actually had no choice- I couldn't install the drivers). In BIOS the USB ports are also set to function at Hi-Speed (480mbps). In case your wondering it takes around 200 minutes to transfer 9 gigabytes of files through the USB ports. Help Greatly Appreciated!
