Actualmente, se llama a usb_submit_urb directamente para enviar urbs de tx diferidas despu\u00e9s de desanclarlas. Por lo tanto, usb_giveback_urb_bh no podr\u00eda desreferenciarla en usb_unanchor_urb y provocar\u00eda una p\u00e9rdida de memoria. Coloque esas urbs en tx_anchor para evitar la p\u00e9rdida y tambi\u00e9n corrija la gesti\u00f3n de errores."
