如何将Arduino nano与QinHeng Electronics HL-340 USB串行适配器连接到OpenWrt？

Question

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

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

但我没有在/dev/tty*

中获得新的串行设备

我安装了kmod-usb-serial。

Answer 1

发布此内容以防其他人有用。答案结果是我需要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
