WSL挂载SD卡备忘-sirgo的博客

当前阶段windows的WSL系统让人又爱又恨。从WSL一路用到WSL2有很多限制，一路用来也是禁了开，开了禁。早期不能和VMware共存，还有网络、磁盘性能低下，端口和主机公用等等一堆问题，隔离性没有完整的虚拟机好。

这里记录下WSL2下如何挂载U盘\SD读卡器（如果挂载硬盘官方有相关文档：关于在 WSL 2 中安装 Linux 磁盘的入门 | Microsoft Learn）

参考：

1、让 WSL 2 支持 USB | Dev on Windows with WSL

2、https://blog.csdn.net/G_C_H/article/details/125939941

方案： usbipd

目前来说，其他方式并不怎么好用。 usbip需要宿主机Windows和WSL虚拟系统都安装usbip，一个作为server一个作为client. 本质就是虚拟了一个usb设置然后通过TCP/IP传输。

1、主机安装usbipd

方式1：在cmd中执行：

winget install usbipd

方式2：https://github.com/dorssel/usbipd-win

测试usbipd是否可用：

C:\Users\kudzu>usbipd list
Connected:
BUSID  VID:PID    DEVICE                                                        STATE
1-5    24ae:2010  USB 输入设备                                                  Not shared

3-4    14cd:1212  USB 大容量存储设备                                            Attached
3-5    04d8:0b29  USB 输入设备                                                  Not shared
5-2    046d:c542  USB 输入设备                                                  Not shared
5-4    1a86:7523  USB-SERIAL CH340 (COM42)                                      Not shared

Persisted:
GUID                                  DEVICE

2、WSL安装USBIP

说明：WSL2内核并没有开启usbip，需要自行编译内核开启

前期准备

//查看系统版本
$ uname -r
4.19.43-microsoft-standard

//安装编译工具链依赖
$ sudo apt install build-essential flex bison libssl-dev libelf-dev libncurses-dev autoconf libudev-dev libtool

下载内核源码并安装

$ sudo git clone https://github.com/microsoft/WSL2-Linux-Kernel.git /usr/src/4.19.43-microsoft-standard
$ cd /usr/src/4.19.43-microsoft-standard

#切换分支
sudo git checkout v4.19.43

# 获取内核配置
$ sudo cp /proc/config.gz config.gz
$ sudo gunzip config.gz
$ sudo mv config .config

#配置内核(也可以直接修改.config)   注：按两次 ESC，选择 Yes 保存并退出
sudo make menuconfig

#开启内核模块，这里的M都改为*编译进内核省事 (按空格可进行切换编译为模块还是内核中)

#编译
sudo make -j 8 && sudo make modules_install -j 8 && sudo make install -j 8

#报错：
BTF: .tmp_vmlinux.btf: pahole (pahole) is not available
Failed to generate BTF for vmlinux
Try to disable CONFIG_DEBUG_INFO_BTF

$ sudo apt install dwarves

使用编译的内核

#复制内核到指定位置
$ cp arch/x86/boot/bzImage /mnt/c/Users/<user>/usbip-bzImage

# 在 /mnt/c/Users/<user>/ 上创建 .wslconfig 文件，并写入以下内容
$ nano /mnt/c/User/kudzu/.wslconfig
[wsl2]
kernel=c:\\users\\<user>\\usbip-bzImage

重启WSL中的系统

C:\Users\kudzu>wsl --shutdown 
C:\Users\kudzu>wsl --list --verbose

#再打开一个cmd窗口启动虚拟系统
C:\Users\kudzu>wsl

使用

1、windows下执行查看设备列表，正常会有设备连接声音，并显示如下(在windows下执行)：

C:\Users\kudzu>usbipd list
Connected:
BUSID  VID:PID    DEVICE                                                        STATE
1-5    24ae:2010  USB 输入设备                                                  Not shared
1-8    8087:0a2a  英特尔(R) 无线 Bluetooth(R)                                   Not shared
1-9    5986:066d  BisonCam, NB Pro                                              Not shared
4-4    14cd:1212  USB 大容量存储设备                                            Attached
3-5    04d8:0b29  USB 输入设备                                                  Not shared
5-2    046d:c542  USB 输入设备                                                  Not shared
5-4    1a86:7523  USB-SERIAL CH340 (COM42)                                      Not shared

2、把usb设备共享给WSL，只需要执行一次(在windows下执行)

C:\Users\kudzu>usbipd bind --busid=4-4

3、挂载(在windows下执行)

C:\Users\kudzu>usbipd attach --wsl  --busid 4-4

4、WSL Ubuntu中查看sh已经挂载到系统

5、WSL中挂载U盘到系统

root@DESKTOP-RSAQBV7:/mnt# mount /dev/sde1 /mnt/xx
root@DESKTOP-RSAQBV7:/mnt# ls /mnt/xx

6、卸载(在windows下执行)：

root@DESKTOP-RSAQBV7:/mnt# usbipd detach --busid=4-4
