Universal Serial Bus (USB) is an input/output port standard for computers and digital equipment, which allows easy transfer of data via a direct connection or cable. Older USB version is 1.1 and the latest is USB 2.0, also known as hi-speed USB. A hi-speed USB host controller refers to the hardware inside the computer that provides hi-speed USB functionality to the ports.
Usually windows XP have the drivers for most of the USB devices otherwise you may also use the Driver's Disk to install the drivers.
You may also ask a local technician to fix and install the USB devices. I can suggest you one at http://www.iyogi.net
