The conga-TR3 offers eight USB 2.0 ports on the A-B connector rows. Four of the USB 2.0 ports can be combined with USB SuperSpeed signals
to create USB 3.0 ports. The USB 2.0 ports support USB 1.1 and 2.0 compliant devices. For more information on how the USB host controllers
are routed, see section 8.5.
