P1: The IOUSBHostControllerInterface command/doorbell blocks ran on an Apple-owned dispatch queue, so callbacks could still fire (and panic in cgo.Handle.Value) after Close deleted the handle. The controller now owns a serial dispatch queue and drains it via dispatch_sync before tearing the wrapper down — the watcher's pattern, extracted into a shared box_usbhost_drain_and_release_queue helper. P2: scatterResponse only bounds-checked ActualLength on IN transfers, so an OUT RET_SUBMIT with a negative or oversized actual_length flowed straight to box_usbhost_endpoint_sm_complete as a wrapped C.size_t. Validation moves into pendingTransfer.accept, which reconciles every response against the request before the length leaves the package. Also wraps cgo.Handle in cgoCallbackHandle so destroy-then-Delete ordering is encoded structurally for both the watcher and the controller.
