Hi,

I'm having an issue with connection to my BBBI over USB. I have installed 
today a new system on the board - Ubuntu 16.04.2 with 4.9.21-ti-rt-r29 
kernel. I've been following the steps from 
here: https://eewiki.net/display/linuxonarm/BeagleBone+Black

Now, that my system is flashed to eMMC and (almost) ready to use, I have a 
strange issue with USB connection. When I plug in my USB cable and connect 
host PC with BBB, after ~30s of booting, my host finally gives me an 
announcement that new wired connection was made. Then when I try "ssh 
ubuntu@192.168.7.2" connection gets refused... Now the funny thing is that 
when I plug in an ethernet cable to BBB, after few seconds I can try again 
with "ssh ubuntu@192.168.7.2" and then it works - until the next boot...

I have copied beaglebone-black-g-ether-load.sh script to my beaglebone and 
am calling it from /etc/rc.local (whose settings I have changed to be 
called after file system is initialized, not as it was set up previously 
after network interfaces are up - then I had even worse situation where I 
have been getting connection timeouts instead of refusal)

I'm out of ideas... I'll appreciate every hint. Below some basic commands 
outputs:
ubuntu@arm:~$ uname -a
Linux arm 4.9.21-ti-rt-r29 #1 SMP PREEMPT RT Sat Apr 15 00:04:36 CEST 2017 
armv7l armv7l armv7l GNU/Linux
