USB Connectors
Your system contains two Universal Serial Bus (USB) connectors for attaching USB-
compliant devices. USB devices are typically peripherals such as mice, printers,
keyboards, and system speakers.
NOTICE: Do not attach a USB device or a combination of USB devices that
draw a maximum current over 500 milliamperes (mA) per channel or +5
volts (V). Attaching devices that exceed this threshold may cause the USB
ports to shut down. See the documentation that accompanied the USB
devices for their maximum current ratings.
If you reconfigure your hardware, you may need pin number and signal information for
the USB connectors. Figure B-6 illustrates the USB connector and Table B-5 defines
the pin assignments and interface signals for the USB connector.
