Hi there, I need to backup my USB storage(a partitioned 64G SDXC card used in my Raspberry Pi, adapted to PC by the built-in USB SD card reader) by dd tool in WSL 2. I followed Connect USB devices | Microsoft Docs, used usbipd to attach my USB storage to WSL lightweight VM:

and the USB storage has shown up in lsusb output in WSL 2:

But no block file appears under /dev directory. Could you please tell me how to access my USB storage devices in WSL 2? Thanks.

Thanks for reporting this @tnqzh123.

This isn't officially supported but I think it should work. Can you share the output of dmesg ? There might be something useful in there

Hi @OneBlue

This is the output of dmesg:

And I found that it seems USB storage support is not enabled by default in WSL's kerenel:
https://github.com/microsoft/WSL2-Linux-Kernel/blob/918dbaa9fa4aa665c9e5fe44489dd453da7cadeb/Microsoft/config-wsl#L2374-L2380

Does this mean I need to build my own kernel to support USB storage?

[tnqzh123]

Hi @OneBlue

I tried to build my own kernel with USB_STORAGE enabled, and it works - I can get the block files under /dev directory.

But I get another problem now: when I try to access the SD card(e.g. mount or fdisk), it will be detached, and WSL will give me an error(e.g. device does not exist). Here is the output of dmesg:

The SD card reader(Genesys Logic USB2.0 Card Reader) is built-in my Lenovo YOGA 14sARE 2020(or, in the outside of Mainland China, Lenovo YOGA Slim 7 14ARE05). I've tried use another USB SD card reader(Genesys Logic USB3.0 Card Reader), it works normally. Is this problem caused by the built-in SD card reader, or WSL, or USBIPD-WIN?

[fletchersarip93]

This is a workaround that works for me: https://github.com/jovton/USB-Storage-on-WSL2

[Kilento]

Maybe it's better way to solve this issue for those who come after. https://dowww.spencerwoo.com/4-advanced/4-4-usb.html#usbip-win

[petersladek]

What a shame this doesn't work OOB. Needed to change dietpi wifi settings on sd card... Ended up using linux in VM.

[MV10]

Ridiculous that this doesn't work.

[itsdotscience]

updated #11335 w/ commit and temp. gist to build the modules .. currently presumes you've already setup the env to build it though. Confirmed mount and fdisk worked without issue as well.

[rs38]

(for USBIPD)
wouldn't it be possibe to add the USB-Mass storage as a module with sudo modprob?
