Note: The USB chip on your system may have a limitation on
the number of USB devices it will support. Normally,
only five USB-4711A devices can be supported.
Note: The power output of an USB port is 500 mA, while the
USB-4711A requires 360 mA (typical). This means that
if an USB hub is used, it will need an external power
supply to support more than one USB-4711A device.
