The I/O Server has four USB 2.0 compliant ports. The left two ports
labeled USB1 and USB2 are high retention USB ports. These ports
require an additional 50% of force to insert and remove the cable
connections as compared to the standard USB ports labeled USB3/4.
Each USB port can source up to 500mA of current. USB devices that
exceed the maximum current are automatically disabled via the hardware.
The pin connections and description for the USB connections are shown in
the figures and table below.
