→USB Ethernet card test
# The '''currently tested''' and usable USB Ethernet cards are as follows. Among them, the RTL8153 USB Gigabit network card can be used normally when inserted into the USB 2.0 Host interface of the development board for testing, but the speed cannot reach Gigabit. Please note this.

<li><p>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.</p>
