Ma carte SD ne se monte pas

Bonjour tout le monde.
J'ai un HUB USB qui comprends 3 ports USB + un lecteur de carte SD (4e port USB).

Il est branché et bien détecté par Ubuntu :

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 037: ID 03eb:0902 Atmel Corp. <= Celui là
Bus 002 Device 002: ID 062a:0102 Creative Labs 
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Les 3 ports USB fonctionnent mais je n'ai aucun retour lorsque j'insère une carte SD.
Le dmesg indique des erreurs :

j'ai trouvé une commande mais qui n'a pas fonctionné chez moi :

modprobe -r ehci_hcd
FATAL: Module ehci_hcd not found.

Merci à vous.
