NAME
usb_copy_descriptors - copy a vector of USB descriptors
SYNOPSIS
struct usb_descriptor_header ** usb_copy_descriptors(struct usb_descriptor_header ** src);

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