Please be aware that USB 3.0 connectivity can be obtained only in case that it is supported by the COM Express module plugged onto the Carrier
Board.
In case the COM Express module used doesn't offer USB 3.0 ports, it will be always possible to use USB 2.0 ports, simply by plugging an USB 2.0
cable.
Avoid using USB 3.0 cables if the COM Express module used doesn't offer such an interface.
