Arduino nano如何与秦恒电子HL-340 USB串口适配器连接到OpenWrt？

Question

当我将 USB 接口从我的 arduino nano 连接到我的 openwrt 路由器时，命令 lsusb 显示：

Bus 001 Device 003: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter

但是我在/dev/tty*

中没有得到新的串口设备

我已经安装了kmod-usb-serial。

张贴此内容以防对其他人有用。答案原来是我需要 kmod-usb-serial-ch341 内核包：

opkg install kmod-usb-serial-ch341

HL-340 是 CH 340 兼容设备。

安装 ch341 驱动程序后，nano 显示为 /dev/ttyUSB0，默认为 115200 波特。来自 dmesg
