int usb_string_ids_tab(struct usb_composite_dev * cdev, struct usb_string * str);

cdev

the device whose string descriptor IDs are being allocated

str

an array of usb_string objects to assign numbers to

single threaded during gadget setup

usb_string_ids() is called from bind callbacks to allocate string IDs. Drivers for functions, configurations, or gadgets will then copy IDs from the string table to the appropriate descriptors and string table for other languages.

All string identifier should be allocated using this, usb_string_id() or usb_string_ids_n() routine, to ensure that for example different functions don't wrongly assign different meanings to the same identifier.
