Hello everybody!
I'm new to this list and am not absolutely sure this perhaps hasn't
been discussed earlier....
I've got a Jenoptik JD C 2.1 LCD digicam which acts as an ordinary
storage device (win2000 can use it - without any extra drivers - as
a normal removable media).
Under my Linux (SuSE 8.1/Suse-Std-Kernel 2.4.19) it also seems to be
initialy detect right...

It also seems to detect its first partition (as sdb1)...but then
there come a lot of messages of my parpor-zipdrive (my sda / because
it has no disc inserted) and after that linux seems to have trouble
getting the partition table of the usb storage device:

- ------snip--------
BUT: I found a _very dirty_ way to get access to the device:
First i catch an image of the whole device:
sg_dd if=/dev/sg3 of=/root/camera.img
Then i cut off the first 16k (16384 Bytes) !! =>camera2.img
_Now_ i can mount that file:
mount -o loop -t vfat /root/camera2.img /mnt/camera
PLEAAAAAAAAAASE can anybody of you usb-gurus ;-) tell me a way - now
that i know i just got to throw the first 16k away - to directly
mount the device???
Very kind regards....
Frank
