Hi,

Yes, you can see if your board is working as a USB 3 device in Control Center. If after downloading firmware you select the Descriptor tab in Control Center under the 'Device' heading you will see bcdUSB = "03 00". There will be addtional descriptors displayed if the device is USB 3, for example BOS and Endpoint Companion descriptors. Also if you download the slave fifo example the packet size will be 1024. I've attached a screenshot of Control Center to show some of this.
