3.11.3. USB Ethernet card test

1) The usable USB Ethernet cards that have been tested so far are as follows. Among them, the RTL8153 USB Gigabit network card can be used normally when it is inserted into the USB 2.0 Host interface of the development board, but the speed cannot reach Gigabit.

Please note:

model RTL8152B USB 100M network card - serial number 1

model RTL8153 USB Gigabit LAN - serial number 2

2) First insert the USB network card into the USB interface of the development board, and then insert the network cable into the USB network card to ensure that the network cable can access the Internet normally. If you can see the following log information through the dmesg command, it means that the USB network card is recognized normally.

orangepi@orangepi:~$ dmesg | tail
[ 121.985016] usb 3- 1: USB disconnect, device number 2

[ 129.892583] IPv6: ADDRCONF(NETDEV_CHANGE): enx00e04c362017: link becomes ready

3) Then you can see the device node of the USB network card and the automatically assigned IP address through the ifconfig command

orangepi@orangepi:~$ sudo ifconfig
