.SH "DESCRIPTION"
.PP
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\&.
