It seems that both the SCK pin and interrupt pin are not configured on your sketch.
Here is the good configuration in the Arduino sketch:
// Singleton instance of the radio driver
// "SPI Chip Select" RF22 pin is wired on Teensy pin "SS",
// "IRQ" RF22 pin is wired on Teensy pin "9"
setup(), before calling
After this changes, the device_type failure should be fixed.
