to try mitigating the USB upload problems on Windows and OSX (which seem to have increased instead than being resolved) we are asking you to test an updated version of dfu-utils binary.
You can download the files from here dfu-utils-cross/distrib at master · arduino/dfu-utils-cross · GitHub
Make sure you are running Curie core version 1.0.5; download the dfu-util executable for your platform and overwrite the one you'll find in
WIN: C:\Users\yourUsername\AppData\Local\Arduino15\packages\Intel\tools\arduino101load\1.6.4+1.18\x86\bin\ OSX: /User/$yourUsername/Library/Arduino15/packages/Intel/tools/arduino101load/1.6.4+1.18/x86/bin Linux: ~/.arduino15/packages/Intel/tools/arduino101load/1.6.4+1.18/x86/bin
Please report here your results
Thank you very much
For the brave:
the binaries has been packaged in an handy json for board manager:
This will trigger a fake update of the core containing the updated tools (no need to update anything manually).
To revert to mainline (once 1.0.6 is published) remove the Curie core then remove the line from Additional json.
