Special Note: USB Drivers come with the operating system and have to be loaded when the computer boots up. As a result, no USB devices can be used until after boot up. It is not possible to boot from an external CD-ROM or hard drive connected through a USB port. Also, if booting up requires a keystroke, the keyboard connected through a USB port would not work for this. A keyboard would need to be connected to the regular keyboard port for this.

USB Notes:

• USB peripherals can connect either to a computer's port or to a hub.
• If the computer doesn't have enough ports for all the peripherals, a hub is necessary.
• Maximum length on individual cables is 5 Meters.
• No terminators are needed on this bus.
• The A (flat) type port would be considered the "out" port on a computer or hub.
• The B (square) type port would be considered an "in" port on hubs or peripherals.
• A typical USB "out" (Type-A) port can provide up to 500mA.
• The speed is 12 Megabytes per second, the maximum number of peripherals to a controller is 63 (hubs needed when the computer runs out of ports).
