Error in initializing network parameters

[Deval Shah]

I ran both the dhcpcd examples. The boot logs are below. I am seeing the
same problem in these two examples too. Test program tries to get the
network interfaces but it is not found since the USB initialization is
still left.

Any other way to solve this problem ? Any example of mentioned routing
socket ?
