I’m trying to flash firmware onto a new Boron device using USB and the particle cli. It says “No DFU device found”.

I am on Windows 10. The Boron DFU Mode device shows up in the Device Manager under Other Devices. It has a warning triangle on it.

I am able to get device info when it goes into listening mode. However, I’m not sure how to put the device into listening mode. It just seems to go into listening mode after a minute or so. The docs do not give any indication on how to enter listening mode.

Any suggestions or advice are appreciated.

This will occur under Windows. There will be an update to the Particle CLI to fix this soon, however for now:

- Download and run the Zadig utility: [http://zadig.akeo.ie/](http://zadig.akeo.ie/)
- Map Boron DFU Mode (also Argon and Xenon) to libusbk:

- Quit Zadig and now DFU should work:

```auto
dfu-util -l
