USB Connectors
The system's USB connectors support USB-compliant peripherals such as keyboards, mice, and printers and may also support USB-compliant devices such as
diskette drives and optical drives.
NOTICE:
Do not attach a USB device or a combination of USB devices that draw a maximum current of more than 500 mA per channel or +5 V. Attaching
devices that exceed this threshold may cause the USB connectors to shut down. See the documentation that accompanied the USB devices for their
maximum current ratings.
