I just bought a Nikon Coolpix 2100 digital camera. It is, of course,
connected to the computer via USB. I haven't used USB before, so I would
be grateful if someone could give me a hint how to configure the kernel
to activate USB and enable me to connect to the camera. I intend to use
modules (which ones?). Should I use a particular software to read the memory of the
camera? I use SL8.1.

Many thanks

If you have not recompiled your own kernel and using an stock kernel, USB
support should be enabled. You probably would not have to worry. All you
have to do is to mount your camera. check /var/log/messages to see which
device is your camera (sda1?)

mount -t vfat /dev/(sda1?) /mnt/camera

should do it.

You may need to compile the usb-storage module ... Though that MAY be in
there too ... the USB howto on LDP covers the necessary points.

You will need to get "Hot plug" support running, if i remember correctly
slack-8.1 does not have hotplugging support as default, (altho') i could
be wrong.
You would also need usb-storage if its not already there, check your
/lib/modules/kernel-version/kernel/drivers/usb directory for it.

Your camera is seemingly not (yet) supported by gphoto2 so you will need
to mount the camera by hand and copy its contents to whereever you want.

I wrote a small howto about a simalar camera its to be found at;

nice, i've get the CP4300 myself.
but i don't connect it yo my pc directly, there's something scary
about (un)plugging that cable into your camera all the time. most
people (and i'm one of them) will recommand you to get a cardreader,
that you keep plugged in to your pc. then just insert your CF card
into that one.

that's what i do.

and most CF readers are just faster than the camera itself

> You will need to get "Hot plug" support running, if i remember correctly

no, you don't *need* hotplug installed. it's not installed overhere,
and everything is working just file without it.

you can just mount/unmount load/unload it yourself.

however, you do need "support for hotpluggable devices" in your
kernel. and ofcourse usb-storage

that's about it

I've got a CP4300 as well. It works better with Linux than it does with
Windows98. When I plug it in to the USB port, it comes up as /dev/sda.
I just mount it, copy the files out, and umount.

The camera is recognised as a scsi device, in /proc/bus/ there is an
entry for USB but the damn thing wouldn't let the camera mount. I tried
/dev/sda1 and a host of other devices. The message always is:

/dev/sda1 is not a valid block device

There are three modules loaded: usbcore, usb-storage and usb-ohci. Maybe
the reason is SL8.1 ?

Of course, the reason is not SL8.1, it's me. I didn't enable SCSI support
for hard disks (which is needed to make sda1 a recognised block).

Thanks for your help

How about loading scsi modules.?????
