The Beaglebone White - first power up

When I find a USB cable and plug the thing into my linux system, I see the following (and a lot more!) appear in my log file. I find this a little surprising given that there is no SD card or any kind of executable image. However I do get a linux kernel exception on my host when it tries to set up some kind of network with device enp0s29u1u8u2 (renamed from usb0). Maybe this would not happen with a proper image.
