All you need is a mini (not micro) USB cable. That will both power it up and give you a console. I looked for a row of 6 pins for a console like the BBB. There is no such thing. I then suspected that the 10 pin connector next to the network connector might be it. No it is not.
It does have a barrel jack for power (that I assume is 5 volts), but I have never used it.
The "white" has an FTDI FT2232 chip on the board and this gives you both a serial console (at 38400 baud) as well as a second USB device that will serve as JTAG (which is very interesting).
Back in 2017, I put an image I found onto an SD card, which is still in the unit. Once I look at the console, I see:
Debian GNU/Linux 7 beaglebone ttyO0 BeagleBoard.org Debian Image 2015-10-30 Support/FAQ: http://elinux.org/Beagleboard:BeagleBoneBlack_Debian default username:password is [debian:temppwd] The IP Address for usb0 is: 192.168.7.2I type "root" and am logged in without a password.
There is plenty of activity from the four LED. I have no network cable attached, but this thing might be doing some crazy network over USB thing. (See below, something like this is indeed going on).
There is a file /uEnv.txt, so I could perhaps get this thing doing network boot for Kyu if I was eager to play around.
Here is what I see from /var/log/messages on my desktop system when I plug in the USB cable:
