Debian 9 (Proxmox 5.2): как запретить монтирование сбойной флешки?

Всем привет! Сразу после установки ОС консоль (и лог) непрерывно забивается вот такими сообщениями:

Т.е. некая флешка то появится, то пропадает. Сервер сейчас физически удалён, нет возможности выдернуть коварный девайс. Можно ли как-то «запретить» его использование на уровне ОС?
