✨ NAME ✨

usb_string_ids_tab — allocate unused string IDs in batch 🦋

---

🌸 SYNOPSIS 🌸

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

---

🫶 ARGUMENTS 🫶

• cdev — the device whose string descriptor IDs are being allocated 👑
• str — an array of usb_string objects to assign numbers to 🎀

---

🧚 CONTEXT 🧚

single threaded during gadget setup 💀

---

💖 DESCRIPTION 💖

usb_string_ids is called from bind callbacks to allocate string IDs. no cap, that's the whole setup.

Drivers for functions, configurations, or gadgets will then copy IDs from the string table to the appropriate descriptors and string table for other languages. it's giving "copy the IDs over so everything lines up" energy. ✨

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. fr fr, do it this way so nobody accidentally gives the same ID two different vibes. 🙈
