HI Community, I am asking you for help, because I did not find this topic in the forum yet. I have added Ethernet port as USB stick ( ADE-SG USB 3.0 GIGABIT ETHERNET) on Turris Omnia. I have installed driver from official Turris repository (opkg install kmod-usb-net-asix-ax88179). Because it using Asix gigabit ethernet. I can see that eth3 was added to the interfaces. But whatever I do and add this interface to LAN as additional port or WAN as PPoE, the communication with this interface is inactive even leds on USB device are active. If I add eth3 to LAN interfaces, it is still not visible in switch (Switch0) therefore I think connection does not work. I have also 3G modem in 2nd USB, but if I disconnect 3g modem, the problem is still the same.
It is true I do not see this USB ethernet card in supported devices on official web page, but on other side driver for Omnia is available so somebody has used it before.
I found also strange errors in logs pasted below. Any idea how I would be able to enable this usb ethernet interface?
I specifically need it as WAN port and then I plan to replace 3G modem mwan3 config with this eth3 interface for load balancing between two internet providers. But I start with configuration of interface in LAN mode just to see, if it is working, which apparently don’t, so far 
Below some pasted outputs from console
