[dundee] Problems with USB mass storage device

[Fionnbar Lenihan]

Would like to ask the lists help in sorting out a little problem

Picked up a cheap digital camcorder on ebay (Pocket DV2 from Nisis). 
This has a CF slot and some internal memory and connects via USB.

Thought I would try to interface it with my linux laptop so plugged it
in. 

dmesg gave the following output when I unplugged and replugged


usb.c: USB disconnect on device 13
hub.c: USB new device connect on bus1/1/4, assigned device number 14
usb.c: USB device 14 (vend/prod 0x8ca/0x104) is not claimed by any
active driver.

So it is detected.

The USB view tool in KDE gave the following info

Tried - 

cat /proc/scsi/scsi

[root@localhost fionnbar]# 

Since I have a USB CD burner I guess the 2nd entry is the camera.

I have a Zaurus and a USB trackball in addition to the CD burner.  All
are powered off a Belkin powered hub.

OK so the USB is working as is the SCSI emulation layer.  Looked in /dev
for anything beginning with "s"

[root@localhost fionnbar]# ls /dev/s
scd0    sd      sda1    sound   stderr  stdout  
scsi    sda     shm     sr      stdin 

I then tried mounting each of these on /mnt/camera with the following
result

[root@localhost fionnbar]# mount /dev/sda /mnt/camera
mount: No medium found
[root@localhost fionnbar]# 


The /dev/sda1 entry is a bit of a red herring as i created that by
symblinking to the same file as sda was symblinked to.  Probably silly.

I'm guessing I might need to use mknod but man mknod is a bit terse and
I'm not sure what values I will need to enter.  Obviously it will be a
block device but what about the major and minor numbers?

Would be grateful for any ideas

Thanks
