I'm not sure you're ending up with a sane network configuration using the 
same subnet mask for each, but did you change the udhcpd config file to 
give the host a different ip for each usb connection? The host gets its ip 
from the beaglebone's dhcp server. I say not sane, because the beaglebone's 
wont be able to communicate with each other because there's no route 
between them.

For a more proper (?) configuration, you could use use the 192.168.7.2, 
subnet 255.255.255.252, host ip range of 192.168.7.1 (start and stop in the 
udhcpd config file). For the other (looking at this subnet calculator 
<http://www.subnet-calculator.com/>), 192.168.7.6, subnet 255.255.255.252, 
host ip 192.168.7.5 (start and stop in its udhcpd config file).

I ended up making a python script to set the usb ip based on the hash of 
the board id stored in eeprom so I wouldn't have to worry (too much, only 
14 bits) about any two beaglebone's clashing
