SerialNumber at Leonardo

Hello, friends! I have make an analysis of USB-HID discriptor Leonardo-based keyboard and mouse. My question is - where can I find the code that sets the value of the parameter “iSerialNumber” in USB_HID Discriptor. (screenshot). The default is “HIDFG” for Leonardo.

Thank you!


I have found solution there Arduino\hardware\arduino\avr\libraries\HID\src\HID.cpp
