The user is encouraged to take some time and compare the code in the preceding
code examples against the descriptor definitions in the USB Revision 2.0 specification
Section 9-5 “Descriptors” . Comments have been included to make the code intuitive
and easier to reference with the USB specification. Definition sources can be located
by highlighting the definition name and selecting Edit>Find in Files in the MPLAB IDE.
This will locate all instances of the definition within the project and list them in the
Output window.
