5.3.1. Hi-Speed USB 2.0 Ports And Performance
To utilize the enhanced Hi-Speed USB 2.0 performance, your computer must be equipped with a Hi-Speed USB 2.0 host bus
adapter card (either sold separately, or integrated by your computer’s manufacturer) and the appropriate drivers. These host
bus adapter cards, which include one or more USB ports, are shipped with special Hi-Speed USB 2.0 drivers that enable the
computer to control the card. These drivers must be installed in order for USB 2.0 devices connected to the port to work at
their correct speeds.
Computers running Windows 2000 and Windows XP automatically manage Hi-Speed USB 2.0 devices and drivers.
Mac OS 9.x does not support Hi-Speed USB 2.0 functionality, and all Hi-Speed USB 2.0 devices will only operate at the
original USB specifications. Mac OS 10.2.7 and later supports Hi-Speed USB 2.0, and Mac OS 10.x also supports Hi-Speed
USB 2.0, but you will have to purchase a third-party PCI or PC Card and appropriate drivers.

5.3.2 Computer With Only USB Ports
If your computer is only equipped with a USB port, connect via the USB cable provided with your drive. Hi-Speed USB 2.0 is
backward compatible and can be used in USB ports. Again, you will be limited to USB speeds and performance.
Another alternative is to purchase a Hi-Speed USB 2.0 host adapter card that you would install into a PCI or PCMCIA slot on
your computer, thereby allowing your computer to take advantage of the performances that FireWire and Hi-Speed USB 2.0
have to offer.
