Problemi con USB
Ciao a tutti,
sto cercando di far vedere alla mia Sid un lettore Superdisk Imation
LS-120, che, a quanto leggo su www.linux-usb.org dovrebbe essere
pienamente supportato dl driver. Ho provato prima con una "penna" usb ed
e` andato tutto liscio: con mount /dev/sda1 /mnt sono riuscito a montare
la penna come se fosse una partizione scsi.
Con il superdisk, che contiene un floppy preventivamente formattato
ext2, invece ottengo il seguente errore:
murena:/home/rick# mount /dev/sda1 /mnt/
mount: /dev/sda1 is not a valid block device
Credo di aver abilitato tutte le opzioni necessarie nel .config del
kernel (2.4.19), dato che la penna funziona, per cui mi sto chiedendo
dove possa essere il problema. L'output di dmesg relativo al driver usb
e`:
