我有一个西佩德 RV 86设备，这是一个 RISCV 64 位。在此，我运行一个最小的 Debian 操作系统，让我可以通过 USB 接口登录，因为设备显示ttyUSB0在主机 Linux PC 上。
当我尝试启动网络时，我偶然发现了这个错误：
# ifconfig

# ifup usb0
ifup: unknown interface usb0
使接口已知后/etc/network/interfaces.d/usb0使用：
auto usb0
iface usb0 inet dhcp
...我得到：
# ifup usb0

我知道我的 DHCP 服务器正在运行并工作，其他客户端也工作正常。我还看到设备上的网络 LED 闪烁，表明存在活动。
如何在该设备上联网？

在启动过程中，我还看到了这一点：

不幸的是，TPLINK dhcp 服务器日志记录严重缺乏......它没有显示太多内容，除了：
