I'm using multiple BBB's (Rev C), communicating with them from my Mac (OSX 10.9.3) over USB using the HoRNDIS drivers. The BBB's are running Debian, and so I want to manually assign them all different static IP's. However, I can't get the IP to be anything but 192.168.7.2. Changing the /etc/network/interfaces file to have an ip of 192.168.7.10 does nothing:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
#auto eth0
#iface eth0 inet dhcp
# Example to keep MAC address between reboots
#hwaddress ether DE:AD:BE:EF:CA:FE

auto eth0
iface eth0 inet static
address 192.168.2.2
netmask 255.255.255.0
network 192.168.2.0
broadcast 192.168.2.255
gateway 192.168.2.1

# WiFi Example
#auto wlan0
#iface wlan0 inet dhcp
#    wpa-ssid "essid"
#    wpa-psk  "password"

# Ethernet/RNDIS gadget (g_ether)
# ... or on host side, usbnet and random hwaddr
# Note on some boards, usb0 is automaticly setup with an init script
# in that case, to completely disable remove file [run_boot-scripts] from the boot partition
iface usb0 inet static
    address 192.168.7.10
    netmask 255.255.255.0
    network 192.168.7.0
    gateway 192.168.7.1

Indeed, there was a file in the boot partition that I also changed, with no result:

#!/bin/bash

# Update /etc/network/interfaces to add virtual Ethernet port
cat >>/etc/network/interfaces <<EOF

iface usb0 inet static
  address 192.168.7.10
  netmask 255.255.255.0
  network 192.168.7.0
  gateway 192.168.7.1
EOF

EOF

#!/bin/bash

BLACK=""
if [ "${ISBLACK}" = "BBBK" ] ; then
    BLACK="Black"
fi
if [ "${ISBLACK}" = "BNLT" ] ; then
    BLACK="Black"
fi

modprobe g_multi file=/dev/mmcblk0p1 cdrom=0 stall=0 removable=1 nofua=1 iSerialNumber=${SERIAL_NUMBER} iManufacturer=Circuitco iProduct=BeagleBone${BLACK} host_addr=${DEV_ADDR}

There is a 3rd file you need to change for BeagleBone Black: /opt/scripts/boot/am335x_evm.sh

I found it here: http://ewong.me/changing-usb0-ip-address-on-the-beaglebone-black

While this link may answer the question, it is better to include the essential parts of the answer here and provide the link for reference.  Link-only answers can become invalid if the linked page changes.  For example, edit your answer to describe the /opt/scripts/boot/am335x_evm.sh file and the changes that need to be made. –  G-Man Apr 8 at 0:37
