Mask:255.255.255.252 ^^ Will be a problem.
This mask means you have the ability to use 3 address, of which one is reserved for the broadcast "IP" Which is not usable by an interface. 192.168.7.0. Which, I'm not a network guru, and I could be remembering incorrectly. You could try loosing that last field from 252 to 251m and see if that works. In an attempt to fix your multiple USB interfaces on the first BBB try to disable the generic start up service temporarily. This can be done by issuing the command: systemctl disable generic-board-startup.service With elevated commands. reboot the board, and try again. If neither interface comes up after a reboot, then you can reenable the service by running: systemctl enable generic-board-startup.service On Fri, Jan 20, 2017 at 5:12 PM, Bert Beckmann <[email protected]> wrote: > 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.
