[yocto] USB Ethernet problems

[Iorga, Cristian]

Hello,

Do you use connman as the network manager?

Hi. In our configuration we do not have an on-board Ethernet device. It connected to the USB-host adapter.
It seems that probing of such devices are done very late in the kernel boot-up which means it gets out of sync with the network init script(s)
and the NIC thus has to be brought up manually after boot.

Is there some way to configure a system through Yocto to handle this scenario?
