Feather M0 spi

[DaveCalaway]

• Arduino board: Adafruit Feather M0 basic

• Arduino IDE version : 1.8.5

I use the example "readMifareClassic" in this library. I checked the compatibility in the main page, i attached the device with SPI, but the compiler give me this error: ` /tmp/arduino_modified_sketch_622904/readMifareClassic.pde: In function 'void setup()': readMifareClassic:67: error: 'SerialUSB' was not declared in this scope

I had a similar issue and just commented out the SerialUSB line. After doing that the examples worked for me.
