Replace all fastDigitalRead/Write() with READ/WRITE() Define SCK_PIN, MISO_PIN, MOSI_PIN in pins.h if not already defined in the pins_*.h files. Remove these conditional pin definitions from the pin-files. They are now always defined. Define separate sets of SPI-pins for AT90USB with and without Teensy support in fastio.h. Likely this was the main reason for all that confusion about the AT90USB-SPI pins.
