So, you would connect these boards just like you would connect a beaglebone
to a PC. The "client" would be connected to the USB mini, while the "host"
would be connected to the full sized USB port. There is a catch here
however. The "host" Beaglebone would have to be power by the barrel jack,
or through the P9 header with probably a 2A power supply - To be safe. This
is because the "client" will probably want to power it's self over the USB
port. Additionally, if you're going to run more than just the basic
hardware on the client. You're going to need more than 500mA where, I'm not
sure how it works when you have both USB and the barrel jack plugged in at
the same time.
As far as configuring the interface for networking. I always hard coded
this myself in /etc/network/interfaces like so:
PC side:
william@eee-pc:~$ tail /etc/network/interfaces
auto usb0
allow-hotplug usb0
iface usb0 inet static
address 192.168.7.1
netmask 255.255.255.0
network 192.168.7.0
gateway 192.168.7.1
Then the beaglebone "client" side(USB mini) would be the same, except the
"address" would be 192.168.7.2. Configured this way, there is no need for a
DHCP server on either end.
