Hello,
sorry to disturb here, but I couldn't find any help in the users mailing
list, so, as a last resort, I try with developers
I am trying to use a Superdisk Imation
LS-120 drive, that, as far as I can read on www.linux-usb.org, should be
fully supported by usb mass storage driver.
I have previously tried with an usb pen, and everything was okay: with
'mount /dev/sda1 /mnt' I have been able to mount the pen as a scsi
partition.
Instead with the superdisk, which has inside an ext2 floppy disk, I get
the following error:
murena:/home/rick# mount /dev/sda1 /mnt/
mount: /dev/sda1 is not a valid block device
The output of dmesg related to usb generic driver
is:

If I try a check of /proc I have:
murena:/home/rick# cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: Model: Rev:
Type: <NULL> ANSI SCSI revision: ffffffff
while a 'cat /proc/bus/usb/devices' blocks the terminal. It is like if
the driver doesn't succeed the initialization, as it appears from lsmod:
murena:/opt/slmdm-2.7.2_i386# lsmod|grep usb
usb-storage 44908 1 (initializing)
Any help will be appreciated.
Bye,
Riccardo
