Universal Serial Bus Interface - HP 8100 - Elite Convertible Minitower PC Technical Reference Manual

5.6 Universal Serial Bus Interface

The Universal Serial Bus (USB) interface provides asynchronous/isochronous data transfers with
compatible peripherals such as keyboards, printers, or modems. This high-speed interface
supports hot-plugging of compatible devices, making possible system configuration changes
without powering down or even rebooting systems.
These systems provide ten externally-accessible USB ports; four front panel USB ports (which
may be disabled) and six USB ports on the rear panel. In addition, these systems support a media
reader accessory that uses two USB ports through a system board header connection. The USB
2.0 controller provides a maximum transfer rate of 480 Mb/s. Table 5-5 shows the mapping of
the USB ports.
