Using Arduino 1.8.19 the example code for reduced_cpu_block does not compile for Teensy 4.0:
sketch_oct02a: In function 'void loop()':
C:\Program Files (x86)\Arduino\hardware\teensy\avr\libraries\Snooze\src/hal/TEENSY_40/hal.h:36:21: error...
Is there any way to wake a T4 or 4.1 when there is incoming USB traffic? The sleep library documentation states that usbSerial does not wake the Teensy.
