+            SDL3 ${{ inputs.sdl3_version }} built with static libusb support.
+
+            Changes from official SDL3 prebuilt packages:
+            - `HAVE_LIBUSB=1` — libusb support compiled in
+            - `SDL_LIBUSB_DYNAMIC` undefined — libusb statically linked into SDL3.dll
+            - No `libusb-1.0.dll` dependency needed at runtime
+
+            This enables support for devices that require libusb on Windows, such as:
+            - Nintendo WUP-028 GameCube Controller Adapter (with WinUSB driver via Zadig)
+            - Other libusb-whitelisted devices
+
+            Based on upstream: https://github.com/libsdl-org/SDL/releases/tag/release-${{ inputs.sdl3_version }}
