SDL_HINT_HIDAPI_LIBUSB_WHITELIST(3)

💖 SDL_HINT_HIDAPI_LIBUSB_WHITELIST 💖

okay bestie, welcome to the SDL_HINT_HIDAPI_LIBUSB_WHITELIST page, straight out of the SDL3 function docs, and yes it's a whole vibe 💅

---

✨ NAME ✨

SDL_HINT_HIDAPI_LIBUSB_WHITELIST — a variable that controls whether HIDAPI uses libusb only for whitelisted devices 🦋

---

✨ SYNOPSIS ✨

#include <SDL3/SDL_hints.h>

#define SDL_HINT_HIDAPI_LIBUSB_WHITELIST "SDL_HIDAPI_LIBUSB_WHITELIST"

like, that's the include, that's the define, that's the whole entrance 🎀

---

✨ DESCRIPTION ✨

so here's the tea 🍓: by default, libusb only gets used for a few devices — the ones that literally need direct USB access. no cap, that's the factory setting.

this variable can be set to the following values:

• "0" — HIDAPI will use libusb for all device access 🔥
• "1" — HIDAPI will use libusb only for whitelisted devices. (this is the default 👑)

⚠️ okay so this is the important part, do not skip it: this hint should be set before SDL is initialized. before, bestie. BEFORE. set it early or it's giving too-late energy 😭

---

✨ AVAILABILITY ✨

this hint has been around since SDL 3.2.0 🌸 so if you're on something older… yeah, it's not there, sorry babe 🙈

and that's the whole page, mwah 💋 — brought to you by Simple Directmedia Layer, version SDL 3.4.18. go set your hints before init, stay iconic, periodt 💜✨
