Following the flashing guide for Linux, the patched dfu-programmer mentioned in https://github.com/borgestrand/sdr-widget/blob/audio-widget-experimental is nowhere to be found /AW_readme.txt#L404 seeing as the old download resource is down.
The new download resource doesn't have it.
Are any of these https://sourceforge.net/projects/dfu-programmer/files/dfu-programmer/ OK to use?
