I have the Teensy 4.0 with the Audio Board for 4.0
Trying to compile the Code Example:
Example/Examples for Teensy 4.0/Audio/HardwareTesting/PassThroughUSB
On a fresh installation of Arduino 1.8.10 / Teensyduino 1.49 on Windows 10
Documents/Arduino/libraries folder is empty
Arduino throws the following error:
Please note the odd and incomplete statement: "Used: C:\Program" ...
Using the Windows Explorer search on C:\ searching for "serialflash.h" only yields a result in
C:\Program Files (x86)\Arduino\hardware\teensy\avr\libraries\SerialFlash
