最近迷上了Linux，入了一塊板。電腦使用win7+ubuntu 雙系統，可是調試的時候就麻煩了，ubuntu下寫好sd卡鏡像，調試的時候還要切換到win7，手上的usb轉串口驅動芯片時CH340，于是就想看ubuntu下時候可以安裝ch340驅動。

網上搜了一下，還真有，不過時很早的內容了。

因為屬于小白，所以就摸著走唄...把ch340 一端插入電腦

輸入命令： lsmod | grep usbserial

輸出：usbserial? ?? ?? ?? ???53248??1 ch341

成功發現了設備，識別出時 ch341??是我記錯了？？

輸入：lsusb

輸出一下信息：

Bus 002 Device 003: ID 17ef:4810 Lenovo Integrated Webcam [R5U877]

Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 006 Device 002: ID 1a81:1004 Holtek Semiconductor, Inc.

Bus 006 Device 003: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter

Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

發現了ch341的一些相關信息

輸入命令(查看USB轉串口接入狀態)：dmesg

輸出相關信息，部分信息如下：

[??429.184170] usb 6-1: new full-speed USB device number 3 using uhci_hcd

[??429.345937] usb 6-1: New USB device found, idVendor=1a86, idProduct=7523

[??429.345944] usb 6-1: New USB device strings: Mfr=0, Product=2, SerialNumber=0

[??429.368123] usbcore: registered new interface driver usbserial

[??429.368396] usbcore: registered new interface driver usbserial_generic

[??429.368875] usbserial: USB Serial support registered for generic

[??429.374125] usbcore: registered new interface driver ch341

[??429.374143] usbserial: USB Serial support registered for ch341-uart

[??429.374165] ch341 6-1:1.0: ch341-uart converter detected

[??429.386851] usb 6-1: ch341-uart converter now attached to ttyUSB0

ID信息與lsusb檢測到的一致，ch341-uart converter now attached to ttyUSB0??成功驅動，端口為ttyUSB0

太驚喜了。免的安裝驅動了

下一步，安裝串口終端軟件，搜到了一個minicom，動手試試：

安裝：sudo apt-get install minicom

打印一些信息，輸入‘y’。

等待安裝成功，然后用sudo minicom -s 設置minicom的端口對應到ttyUSB0(對應使用dmesg命令看到的信息)。

出現配置菜單：

選擇“Serial port setup”，出現串口配置菜單：

輸入A，修改serial device 由/Dev/tty0修改為/dev/ttyusb0，波特率等修改為115200 8N1。

硬件連接，上電，成功輸出打印信息，呵呵
