dfu-util does not list devices when Windows-version does

[billbogaiv]

Windows build number: Microsoft Windows [Version 10.0.16299.334]

I am using WSL in combination with a Particle Photon and part of that process involves using dfu-util. This command is used to manage firmware via USB. There are native builds for Windows and Linux. I am using v0.8. When I run the command dfu-util.exe -l on Windows, I see my expected device:

Found DFU: [2b04:d006] ver=0250, devnum=32, cfg=1, intf=0, alt=1, name="@DCT Flash   /0x00000000/01*016Kg", serial="<intentionally omitted>"

When I run dfu-util -l via WSL, I get nothing (no output and no errors). Running this setup in native-Linux works the same as Windows.

Note: I can communicate via serial using /dev/ttyS..., so WSL is at-least "aware" of the device.

No strace log because you deleted the template (natch) but on WSL /sys/bus is an empty directory. #1521, #2195, #2287, #2185 et al.

getdents returned nothing. It would be easier to do ls /sys/bus.

[DanielGGordon]

The response here is a little cryptic - what is the solution for this? I also have firmware that needs to be flashed with dfu-util and it is not being picked up in WSL

[MichaelShmalkoProCoder]

Any updates on this one?
