A quick check with Google indicates that Ubuntu uses /etc/network/interfaces to control the devices. Once that is correct, you should be able to 'sudo /etc/init.d/networking restart' to start the network. If the server is properly configured, the network should start on boot. BTW, the dmesg buffer is circular. All that usb monitoring output has completely filled the buffer, and it contains no useful information.
