Make parameter Serial number - "Not specified" (Leonardo)

Official Hardware Classic Leonardo
1

Hello! I'm using IDE 2.1.0 with Leonardo's board and using the USB HID keyboard and mouse emulation library. I know where i can set the "Serial Number" parameter of my USB HID Device - in PluggableUSB.cpp :

for example - the code below will set the parameter "Serial number" of the device - 01296

virtual uint8_t getShortName(char *name) { name[0] = '0'; name[1] = '1'; name[2] = '2'; name[3] = '9'; name[4] = '6';   return 5; }

Well, but how can I make this parameter "Serial number" are "Not specified"? For example - I analyze real USB HID devices - this parameter it says "Not specified", i.e. the parameter is not set. Example1 Example2

I have tried ending the above line like this -

virtual uint8_t getShortName(char *name) { name[0] = '0'; name[1] = '1'; name[2] = '2'; name[3] = '9'; name[4] = '6';   return 0; }

but it had no effect. - it says "String Descriptor 3 (unable to read).

Has anyone successfully resolved this issue?
Thank you!
