molton Toujours dans la tendance... | J'ai un disque IDE 120Go que j'ai mis dans un rack USB supportant l'USB2.0
Sans le module ehci-hcc (support USB2) ce disque est reconnu mais le taux de transfert moyen est en dessous du Mo.
Si j'active le module ehci-hcc le disque n'est plus reconnu.
Voici qqs traces de mon noyau :

Apparement avec l'USB il n'arrive pas a assigner une adresse :
Code :
- USB device not accepting new address=4 (error=-71)
|
Et il essaye deux fois :
Code :
- USB device not accepting new address=5 (error=-71)
