[Clo] Problème avec usb sur un laptop

Dim 9 Sep 01:17:02 EDT 2007

Salutation

J'ai un ordinateur portable de marque Toshiba M40 et j'ai installé 
Ubuntu 7.04 sur celui-ci. Finalement avec l'installation de pilotes 
propriétaires (wireless atheros et vidéo ati ), mon portable fonctionne 
convenablement sous linux, ce qui n'était pas le cas par le passé. 
Cependant j'ai un problème avec les ports usb. Ceux-ci sont reconnus au 
démarrage et fonctionne correctement pendant quelque temps mais au cours 
de la session en cours, ceux-ci deviennent inutilisables car linux 
semble éprouvé de sérieuses difficultés à garder ceux-ci en fonction. 
C'est vraiment frustant de se retrouver sans souris, clavier, ainsi que 
la perte des clés usb. Bref Linux n'est pas fiable sur mon portable pour 
le moment.

J'ai regardé sur internet et j'ai trouvé une information à propos du 
paramètre irqpool qui devrait être transmis au démarrage. Pour le 
moment, je n'ai pas d'idée exact sur ce que fait ce paramètre et 
pourquoi celui-ci serait nécessaire à mon laptop.

Avez-vous des idées sur le sujet?
