USB модем отключается через некоторое время в 12.04

У меня есть USB-модем huawei E1732, и я использую с ним мобильный партнер (предоставленный производителем).
Недавно модем начал отключаться, и сеть не обнаруживается после отключения, и мне нужно удалить его и заново установить, чтобы он работал.
Что я должен сделать, чтобы предотвратить частое повторное отключение?
Также есть ли способ управления моим USB-модемом с помощью терминала?
