reference, the USB Revision 2.0 specification should be opened to Section 9-5
“Descriptors”. This section details the various components required in each type of
descriptor (device, configuration, interface etc.). This usb_descriptor.c file should
be an exact replica of the source file of the same name found in the Framework folder
C:\Microchip Solutions\USB Device - HID - Mouse\HID - Mouse –
Firmware\usb_descriptor.c
This file can be used as a reference during debugging.
