Bonjour,

je suis abonné à l'ADSL chez Cegetel, mon ADSL-modem est un sagem fast 800 USB, et ma machine fonctionne sous linux/debian testing, avec un noyau 2.6.16.

Le modem, y compris le modem fonctionne depuis un an environ.

J'utilisais les sources du driver de debian (compilées avec module-assistant), et le firmwire propriétaire, que j'avais recopié sur ma machine.

Depuis, quelques temps, le modem se met à se déconnecter; ce problème est gênant, vu que la reconection n'est pas automatique.

Que faire?
* Est-ce que ça peut être lié à un téléchargement?
* à la charge de la machine?
* à des problèmes USB?

Comment savoir?

Que faire?

Que signifie «Protocol-Reject for unsupported protocol 0x0»?

Merci.
