@zweistein22 kindly ignore my previous question. I found the answer. It doens't have an extension at all.

Cheers mate !

Same here.
Mounting a USB drive to WSL works with an external USB drive (ext4 FS), but does not work with an external USB flash drive (exFAT FS).
Will try the workaround (use iSCSI to connect drive from Windows to WSL) mentioned above. It's not a solution imho.

Mounting the root partition from a Raspberry Pi (connected via USB after running rpiboot) does not work. I get the same error code as above, even though this is an ext4 partition.

I'm getting the same behavior that andrsmllr mentioned.
Fix this please. Thanks

i think we can solve it
use usbipd

i think we can solve it use usbipd

According to thread (actually referenced above) ....
https://github.com/jovton/USB-Storage-on-WSL2
.... USB/IP not yet supported on WSL2 bc of existing WSL2 limitations.

The solution in said thread is to use iSCSI emulation to get around limitations of both WSL2 & USB/IP.

Same issue. Extremely disappointing. 😭 I needed a win today, but no.

Same issue.
Using iscsi is not a solution. It's a try to get away with bad design.
Very disappointing.

As a workaround I cloned whole sd card to a file and mounted it with sudo losetup -fP --show /mnt/d/backup/rpi5.raw
Then mount ext4 partition:

lsblk /dev/loop0
sudo mount /dev/loop0p2 /home/p/rpi_backup/ext4_mount
