If a second call occurs while the URB is still active (e.g. during rapid firmware loading), usb_submit_urb() detects the active state and triggers a warning: 'URB submitted while active'. Fix this by enforcing serialization: call usb_kill_urb() before submitting the new request. This ensures the URB is idle and safe to reuse.
