I installed OpenWRT 18.06.4 on Asus RT-N18U and connected a Lenovo USB-to-Ethernet network card. I installed proper modules - kmod-usb-cdc-ether and all -usb- modules including usbutils, but the device seems to be not ready for working as a network interface. All I see in system log is:
usb 1-2: new high-speed USB device number 2 using ehci-platform
Nothing about ether. But. On another router, TP-Link TL-WR1043ND I managed to run this USB thing some time ago (about 1,5 years), and it still runs (under OpenWRT 15.05.1 though). I see in system log:
cdc_ether 1-1:2.0 eth2: register 'cdc_ether' at usb-ehci-platform.0-1, CDC Ethernet Device, xx:xx:xx:xx:xx:xx
And here is the question: how can I make the same for my Asus router? What did I miss in installing?
