PLUGIN_HARDWARE_ONCE only suppresses retries of the initial attach; when an established connection later drops, wsk_receive.cpp unconditionally schedules background reattach attempts (~20 tries over ~2 hours) toward this session's dead one-shot loopback port. With ephemeral port reuse those ghost connects steal a later session's Accept and fail its Plugin. Wire up STOP_ATTACH_ATTEMPTS (0x805, present in both bundled driver builds) and cancel the session's exact host/service/busid location before plugout.
