OPL embeds usbd_mini; the post-b1f7ff96 rewrite breaks Wrath of Cortex over USB (TD completes never wake WaitSema). Hardware shows old FreeUsbd usbd + modern usbmass works. Give usbd_mini its own FreeUsbd sources (from 2dc6b32) and keep the SCE rewrite for full usbd. Export table stays 1.2 with stubs for reboot/report/multi-isoc.

usbmass_bdis fine; the rewrite’susbd_minipath is not. Many FreeUsbd-vs-rewrite A/Bs on the rewrite were tried (HCD bring-up, WDH/DoneHead, dual TD queues, embedded ED, hub flush, SetAddress timing, attach/transferedBytes, timerdelay-=1, etc.) — none restore play after the cutscene. Dead list on #908.This does not claim to fix the rewrite; it restores the known-good driver for the mini module OPL actually ships.
