Hi,
you have basically already answered the question. Your devices
are driven by cdc-ether. It cannot assign an IP. After you have
assigned an IP manually, your network is working. Hence the kernel
is fine. Your user space is misconfigured. You need to get help
from the people of whatever network configuration tool you distro
is using.
The USB list is not the place for such issues.
HTH
Oliver
