Chapter 13: USB
Description
Universal Serial Bus (USB) is a hardware interface for low-speed peripherals such
as the keyboard, mouse, joystick, scanner, printer, and telephony devices. USB 1.1
has a maximum transfer rate of 12 Mbits/sec, and up to 127 devices can be
attached. Peripherals can be plugged in and unplugged while power is applied to
the system. The 2060 CPU Card contains two 1.1 compliant USB ports.
The two USB ports are accessed via standard USB connectors on the HDC-18-
Multiport Cable (USB1) and the HDD/FP cable (USB2). Any USB device can plug
into either USB interface, or into a multi-port hub that then plugs into either USB
port.
An operating system capable of utilizing the USB ports and USB devices is
required for USB operation.
Caution
USB devices are hot-swappable when a device is plugged into a
standard USB connector, as pins on the connectors determine the
order in which they make contact. Devices are not hot-swappable
when connected to a non-standard header. You can hot swap a
device through the USB connector on the 2060 Multiport cable, or
through another USB connector wired to the 80-pin header, but you
cannot hot swap at the 80-pin header itself.
