My goal is to change the IP address of USB0.
The Beagle Bone Black run Debian.
I tryed to change /etc/network/interfaces such that default address is 192.168.7.3 instead of 192.168.7.2 as this:
iface usb0 inet static
address 192.168.7.3
netmask 255.255.255.0
network 192.168.7.0
gateway 192.168.7.1
After running
/etc/init.d/networking restart
It was still on 192.168.7.2.
I tryed rebotting, and yet is to no avail.
I tryed to change the IP address in /boot/uboot/scripts/setup-ubuntu-armhf-3.8.13-bone30.sh, but basicly this file overwrites /etc/network/interfaces.
Still after reboot the IP is still 192.168.7.2.
Edit: Also tryed to change the IP in:
/media/Angstrom/usr/bin/g-ether-load.sh /media/Angstrom/etc/udev/rules.d/udhcpd.rules
Which didn’t work.
Tryed to change it in:
/opt/scripts/boot/am335x_evm.sh
And now the network is unreachable:
ssh: connect to host 192.168.7.3 port 22: Network is unreachable

I was having the same problem on:
BeagleBoard.org Debian Image 2017-03-19
The issue turned out to be “connmand” (read it again, it starts with coNN, not comm). It is a horribly named program as it is difficult to research as Google assumed you spelled something wrong.
connman automatically configures wired instances for dhcp despite what is listed in /etc/network/interfaces.
Recommend either disabling it, or adding your interface to be ignored:
/etc/connman/main.conf: NetworkInterfaceBlacklist=SoftAp0,usb0,usb1,eth0
After doing that and restarting, my static IP configured for eth0 in /etc/network/interfaces started working.
