DESCRIPTION

19       usb_string_id() is called from bind callbacks to allocate string IDs.
20       Drivers for functions, configurations, or gadgets will then store that
21       ID in the appropriate descriptors and string table.
22
23       All string identifier should be allocated using this routine, to ensure
24       that for example different functions don´t wrongly assign different
25       meanings to the same identifier.
