I think you need unregister_console(&usbcons);
on disconnect. If the device is reinstalled later,
the console is registered again in usb_serial_console_init().
Until it is unregistered, the console subsystem keeps trying
to write to an ejected usb console.
The check for disconnected state prevents the write call
from causing harm, but it is still making unnecessary calls.
