Where can I get "delay.h" file?

Hi, recently I found this useful project.

I tried to edit "MIDIUARTUSBH.ino.trinket_m0.ino" sketch in order to change the baud rate from 11,5200 to 31,250.
However, I fail when I compile it. Arduino IDE shows an error message as shown below;

C:\Users\NAME\Documents\Arduino\libraries\USB_Host_Library_SAMD\src\usbhub.cpp:18:10: fatal error: delay.h: No such file or directory
#include "delay.h"
^~~~~~~~~
compilation terminated.

I searched the "delay.h" fille with no success. Where can I it? Thanks.

Sorry, I could find the answer in the past post. Just replacing "delay.h" by "delay.c" solved the problem. Thanks.
