If a second call\noccurs while the URB is still active (e.g. during rapid firmware loading),\nusb_submit_urb() detects the active state and triggers a warning:\n'URB submitted while active'.\n\nFix this by enforcing serialization: call usb_kill_urb() before\nsubmitting the new request. This ensures the URB is idle and safe to reuse."
