Setup IP address manyally, e.g. setup IP address as ''192.168.35.100''

```shell
sudo ifconfig usb0 192.168.35.100 up
```

You also need to setup the IP address on your PC, e.g. ''192.168.35.110''

Check network connection:

```shell
khadas@Khadas:~$ ping -I usb0 192.168.35.110

===== Troubleshooting =====

If adb not work on windows, you can edit ''/etc/profile.d/usbdevice.sh'' to comment ''export USB_FUNCS="rndis"'' and reboot.

```diff
diff --git a/etc/profile.d/usbdevice.sh b/etc/profile.d/usbdevice.sh
