Connect USB to Ethernet dongle on E90
This page introduces how to rework the E90 camera to connect an USB-to-Ethernet dongle. This is typically for applications such as FPV or remote command & control that want to use a datalink other than Wifi.
There are two USB ports on the E90: an external port that works as a slave and an internal port works as host. The USB host port is connected to a WiFi device by default. If you want the host port to connect to another USB device, the WiFi device needs to be disconnected first.
1. Disconnect WiFi device by removing the resistor in the red rectangle.
2. Connect the USB device: connect a USB device to test points in the green rectangle.
Kernel Driver Support
The latest E90 firmware loads the smsc95xx USB-to-Ethernet driver by default. It also supports USB2Ethernet drivers AX8817X, AX88179_178A, and NET1080. If you would like to use another driver, please send a request to firstname.lastname@example.org.
This dongle has been tested and verified to work.
