I just tried to reboot my PC and trried it again… Same problem.

This is very wierd that it does not work?I even tried to  
Install a generic USB driver that supports `libusb` . Download [Zadig](https://zadig.akeo.ie/) to install “WinUSB” and [consult this article](https://www.hanselman.com/blog/how-to-fix-dfuutil-stm-winusb-zadig-bootloaders-and-other-firmware-flashing-issues-on-windows) for more information.

And this did not help. The SAME DFU error. I’m stuck here with programming my SWAN. Could it be that I’m missing something in my VSCode PlatformIO instalation on 2 Windows PC’s ???
