USBBlaster-1.0.0 not working for MKR Vidor 4000

Hi @ferdaus89. There was a significant restructuring of the "Arduino SAMD (32-bits ARM Cortex-M0+) Boards" platform at its 1.8.10 release caused by the switch to using the ArduinoCore-API code (AKA "Project Chainsaw")

This broke compatibility with the "USBBlaster" library. A similar thing happened with the MIDIUSB library:

and you can make the same simple fix:

  1. Open this file in a text editor:
    C:\Users\rf\Documents\Arduino\libraries\USBBlaster\src/USBConfig.h
    
  2. Change line 51 from this:
    #include "USB/PluggableUSB.h"
    
    to this:
    #include "api/PluggableUSB.h"
    
  3. Save the file.
