Windows Mount Linux Partition in WSL 掛載 存取 Linux USB SD Card 隨身碟 EXT4
掛載Linux disk in WSL2
網路上有些文章參考了這篇說可以成功掛載linux disk，我實際測試掛載USB linux的結果會發生底下錯誤訊息。
搜尋有哪些磁碟設備
PS C:\Windows\system32> GET-CimInstance -query "SELECT * from Win32_DiskDrive"
DeviceID Caption Partitions Size Model
-------- ------- ---------- ---- -----
\\.\PHYSICALDRIVE1 TS-RDF5A Transcend USB Device 2 15833664000 TS-RDF5A Transcend USB Device
\\.\PHYSICALDRIVE0 NVMe KBG50ZNS512G NVMe KIOXIA 512GB 5 512105932800 NVMe KBG50ZNS512G NVMe KIOXIA 512GB
底下指令掛載磁碟~確有錯誤0x8007000f
PS C:\Windows\system32> wsl --mount \\.\PHYSICALDRIVE1 --partition 2 --type EXT4
系統找不到指定的磁碟機。
Error code: Wsl/Service/AttachDisk/0x8007000f
我個人猜測是他只能掛載磁碟機不能掛載USB或SD Card。
使用USB/IP來掛載 USB Drive/ SD Card
再深入搜尋解法時找到有些人用usbipd來連接USB裝置，但我在試完之後卻發現，lsusb雖然有抓到USB裝置，但是卻沒有dev裝置，sda~sdd都是我本機端的內建磁碟裝置。或者是dmesg 顯示error=remount-ro的訊息，而沒有說USB裝置是哪一個sdx。

但最後面有解決方式，所以這邊還是先一步一步來安裝usbipd。
在WSL輸入底下指令
sudo apt install linux-tools-5.4.0-77-generic hwdata
sudo update-alternatives --install /usr/local/bin/usbip usbip /usr/lib/linux-tools/5.4.0-77-generic/usbip 20
開啟Powershell輸入底下指令
PS C:\Windows\system32> usbipd wsl list
BUSID VID:PID DEVICE STATE
2-2 2109:0100 USB 2.0 BILLBOARD Not attached
2-3 1532:0062 USB 輸入裝置, Razer Atheris Not attached
2-4 8564:4000 USB Mass Storage Device Not attached
2-5 27c6:639c Goodix MOC Fingerprint Not attached
2-6 0bda:554a Integrated Webcam, Camera DFU Device Not attached
2-10 8087:0026 Intel(R) Wireless Bluetooth(R) Not attached
列出你現在有哪些WSL distribution
PS C:\Windows\system32> wsl -l
Windows 子系統 Linux 版發佈:
Ubuntu (預設)
Ubuntu-18.04
docker-desktop
Ubuntu-20.04
docker-desktop-data
PS C:\Windows\system32> usbipd wsl attach --busid 2-4 --distribution Ubuntu-18.04
usbipd: warning: A third-party firewall may be blocking the connection; ensure TCP port 3240 is allowed.
回到WSL看到lsusb有抓到我創見的讀卡機，但卻沒有抓到sdx設備。

sdc 8:32 0 1T 0 disk
sdd 8:48 0 1T 0 disk /mnt/wslg/distro
原來WSL Linux Kernel沒有USB Storage Driver
caspar@Y01467-Caspar:~$ sudo cp /proc/config.gz config.gz
[sudo] password for caspar:
caspar@Y01467-Caspar:~$ sudo gunzip config.gz
caspar@Y01467-Caspar:~$ cat config |grep USB_STOR
# NOTE: USB_STORAGE depends on SCSI but BLK_DEV_SD may
# also be needed; see USB_STORAGE Help for more info
# CONFIG_USB_STORAGE is not set
所以請再繼續參考我這篇文章Windows_wsl_build_kernel來編譯WSL Linux kernel。
編譯完成之後再一次使用USBIPD
結果如下
~$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 363.3M 1 disk
sdb 8:16 0 2G 0 disk [SWAP]
sdc 8:32 0 1T 0 disk

sde 8:64 1 14.8G 0 disk

順利抓到sde設備也出現我sd card的容量。
