[Résolu] bouclage sur "unable to enumerate USB device on port x"
Bonjour à tous.
Je vous fais part de mon problème en espérant que quelqu'un saura me donner une solution.
Hier après-midi, inexplicablement, ma souris USB a cessé de fonctionner.
En regardant de plus près, le problème semble venir de la détection des périphériques sur les ports USB.
Les concentrateurs sont bien détéctés ainsi que le montre un "lsusb" :

[ 272.553031] hub 7-0:1.0: unable to enumerate USB device on port 6.. et ça continue comme ça pendant des pages...
En regardant les journaux système, on se rend compte que toutes 2s à peu près, un nouveau message apparait dans le fichier "/var/log/syslog" de la forme :
unable to enumerate USB device on port xle numéro du port variant entre 2 chiffres qui changent à chaque reboot (peut être une assignation différente des id de port à chaque boot).
et, de temps en temps avec un délai variable, un autre message :
connect-debounce failed, port x disabled... ce qui ne l'empêche pas de continuer invariablement à essayer d'énumérer sur le port soit-disant "disabled".
Petites précisions :
- le même comportement a lieu en session live-cd avec le liveCD Intrepid Ibex.
- je suis en version Intrepid Ibex avec le noyau 2.6.27-11-generic / Gnome 2.24.1
- mon PC est un HP avec un core 2 duo 6400@2.13Ghz
J'ai contourné le problème en ramenant une souris PS/2 de la maison ce qui me permet de bosser quand-même, mais je ne peux attendre aucun soutien de la DSI de ma boite qui ne jure que par Windows (j'ai un peu installé Ubuntu en douce 
).
En gros, ce dont j'aurais besoin, c'est soit d'une solution à ce problème, soit d'une preuve à fournir à la DSI que le soucis est matériel afin qu'ils me changent le PC.
Voilà, merci d'avance pour toute aide...

Re : [Résolu] bouclage sur "unable to enumerate USB device on port x"
Pour essayer d'avancer sur le sujet, j'ai tenté d'installer le logiciel "usbview" disponible via synaptic afin de voir ce qu'il allait me dire. Voici la réponse en image :
Effectivement, quand je vais voir dans le répertoire "/proc/bus/usb", il est totalement vide.
Pensez-vous qu'une réinstallation des paquets liés à l'USB pour corriger le problème ?

Re : [Résolu] bouclage sur "unable to enumerate USB device on port x"
L'avantage d'avoir à ma disposition des brouettes de PC du même modèle que le mien m'a permis de monter un disque dur avec Windows dessus à la place de mon disque Ubuntu.
Le résultat est le même : ni la souris USB ni les clés ne sont reconnues.
En outre, le gestionnaire de périphériques de Windows affiche un joli point d'exclamation jaune sur l'un des concentrateurs racine USB.
J'en conclue donc à une panne matérielle et ai mis le dossier dans les mains de la DSI qui doit venir changer ma CM.
Merci à tous ceux qui se sont intéressé à mon problème faute d'avoir pu y répondre.

Au cas où d'autres tombent sur le même problème, la solution a été de débrancher le PC, puis d'appuyer pendant 20s sur le bouton de mise en route. D'après la DSI, cela a pour effet de décharger tous les condensateurs de la carte mère. Quoi-qu'il en soit, au redemarage, le problème était résolu.
