Zigbee Stick Installation

Need some help!

Just recieved the zigbee dongle cc2531 and tried to set it up. Im having issues trying to locate the dongle. in hardware it comes up under /dev/tty/AM0, but doesnt have a usb number in the details. there is the list of 4 usb ports below but with no info on them.
From the intergrations set up menu i then select the dongle from the drop down (also list it as the texas instrament…)
it scans for a while then comes to another section to select a Zigbee radio and lists other types of dongles inculding the texas instruments. i click the texas one but what ever input i write it doesnt work!

its killing me, something that seemed so simple!
