DESCRIPTION

20       This makes a copy of a vector of USB descriptors. Its primary use is to
21       support usb_function objects which can have multiple copies, each
22       needing different descriptors. Functions may have static tables of
23       descriptors, which are used as templates and customized with
24       identifiers (for interfaces, strings, endpoints, and more) as needed by
25       a given function instance.
