The serial number is zero. The unique identifier is that its usb0.

I may have got my managed/unmanaged terminology confused. Right now,
NetworkManager handles all devices not listed int
/etc/network/interfaces. I have two wired devices, one is my permanent
eth0. eth0 I want nm to manage. The other is the beagle board.
