Darwin URBs handled in concurrent goroutines mutated BoxUSBHostDevice's pipes/interfaces dictionaries without serialization, so SetConfiguration racing with endpoint IO could corrupt them or hand back stale pipes. Guard the collections with os_unfair_lock; keep the slow IOKit calls outside the lock so unrelated endpoints don't stall. Iso IN responses were flat-copied buffer[:actual], losing offsets for multi-packet transfers. Pack the wire payload per IsoPackets[i].Offset/ ActualLength to match Linux's stub_tx.c, and mirror the scatter on the Darwin client side so a future multi-packet emitter is correct.
