For some reason when I plug in my Fuji M603 digital camera it is recognised but no SCSI device is assigned.

This is the output of dmesg:

hub 1-0:1.0: new USB device on port 1, assigned address 2
SCSI subsystem initialized
Initializing USB Mass Storage driver...
scsi0 : SCSI emulation for USB Mass Storage devices
Vendor: FUJIFILM Model: USB-DRIVEUNIT Rev: 1.00
Type: Direct-Access ANSI SCSI revision: 02
WARNING: USB Mass Storage data integrity not assured
USB Mass Storage device found at 2
drivers/usb/core/usb.c: registered new driver usb-storage
USB Mass Storage support registered.

If I try ;

mount -t vfat /dev/sda1 /mnt/usbdrv

the result is ;

sda1 is not a valid block device.

Anybody seen this before?

Having just played around with a few usb CF readers I found one that I had to mount using sdb1, you could try that.. or see what,

cdrecord -scanbus

gives you.

ok I've got a little further now.

I had to load the generic scsi module with "modprobe sg"

Now dmesg says;

"Attached scsi generic sg0 at scsi1 channel 0, id 0, lun 0 type 0"

but sg_map just returns

"/dev/sg0"

so now there is no device mapping for /dev/sg0

What does "cdrecord -scanbus" give you?

Ah bugger....

I found the problem, I didn't load sd-mod. I attached the camera again and did;

modprobe usb-storage
modprobe sg
modprobe sd-mod

and there it was at /dev/sda1.
