Device not recognized after changing device name

[reekystive]

I can compile the unmodified source code correctly and everything works fine. But when I changed the device name in the code, I still compiled correctly, and the device name I changed was successfully displayed in the control panel, but it could not be recognized in the FL Studio software. I want to know how I should change the device name correctly.

This is what I have changed:

Descriptors.c
line 263
const USB_Descriptor_String_t PROGMEM ProductString = USB_STRING_DESCRIPTOR(L"arduino_midi");

Changed to

Descriptors.c
line 263
const USB_Descriptor_String_t PROGMEM ProductString = USB_STRING_DESCRIPTOR(L"My MIDI Controller");

I changed it to a shorter name and it worked fine. But I don't know why this problem occurs.
