Disque USB (encore)

Bonjour,

Sous Debian depuis environ 1 mois, le branchement d'une clef USB
fonctionne parfaitement.
Après branchement de la clef un explorateur de fichier Gnome s'ouvre.

$ cat /var/log/syslog

# umount /media/usbdisk/

En revanche le branchement d'un disque dur externe (archos MiniHD) ne
fonctionne pas alors qu'il fonctionne sous Knoppix (par exemple) sur le
même micro (un portable).
Après branchement il ne se passe strictement rien et

$ cat /var/log/syslog

Il me *semble* pourtant le localiser ici :

J'ai aussi essayé de booter disque externe branché.

Le fichier de configuration que j'ai utilisé pour recompiler le noyau est à l'adresse :
http://linux.spiney.org/debian_gnu_linux_on_an_ibm_thinkpad_t43p_kernel_configuration


Toute suggestion est le bienvenue.
Merci et bon week end.

PS : désolé pour les lignes trop longues.
