so close!
without any kernel changes - I am now seeing usb0 and usb1 in ifconfig on
BBB1 when I connect the 2nd BBB to the first (mini to full).
I assign IP's - I gave 192.168.7.1 to the 2nd BBB.
Maybe netmask / ip #'s are causing problems - will try using .2 and .3 with
mask of 255.255.255.0
what happens now --- if I ssh to 192.168.7.1 expecting to see my 2nd BBB, I
get connected to the BBB I am running on.
so so close!
ah - however - now on the 2nd BBB - no usb0 device shows up. That explains
a little. When the cable is connected, the 2nd BBB drops it's usb0
definition. The 1st BBB get's usb1 added though.
Maybe Robert's mod is needed.
Here are the ifconfigs:
