Received new USB-Ethernet adapter today (MAC: 00:10:13:48:DC:C1), trying it out. When I switch to USB host mode this adapter shows up when I run 'lsusb', however still can't ping across. Running updates now, will download 'arping' to see if I can talk to it from one side or the other.

apt-get update

apt-get install upgrade

Run dpkg-reconfigure tzdata (to change timezone)

apt-get install arping
