This is an overview of how to use the "dc2xx" USB driver with certain
digital still cameras from Kodak and other vendors.
CAMERAS
This driver will mostly be used with Kodak DC-2xx series digital still
cameras, but it should be trivial to tell it about several non-Kodak
USB-enabled cameras.
You'll most likely want to hook it up to recent versions of "gPhoto"
(www.gphoto.org), since version 0.4 and later know how to use it to talk
to Kodak DC-240 and DC-280 cameras over USB.
In addition the DC-220, DC-260, DC-265, and DC-290 are also recognized.
However, like other cameras using the "Digita OS" (from www.flashpoint.com)
there is no gPhoto support for this camera. There is a python script
for accessing these cameras (see archives of the linux-usb mailing list)
and a "Digita Services" library that can also use this driver.
The HP PhotoSmart C500 should also work, since it's another Digita camera
with USB support.
USB HARDWARE
Recent kernels have had no particular problems using this driver with
either OHCI or UHCI chipsets, and have worked on the PowerMac platform.
Note that in some cases changes in BIOS settings may be needed before
your USB works. At least one user has reported a need for SMP-related
settings as well, and some old hardware may not handle USB correctly.
SETUP
Configure in the DC2XX USB driver, and have it in your kernel. It works
as a module, or compiled in directly.
Create at least one device, perhaps like this (both read and write):
# mknod -m 0660 /dev/usb/dc2xx0 c 180 80
# mknod -m 0660 /dev/usb/dc2xx1 c 180 81
...
NOTE: you would normally configure PAM so that the user logged in at
the console is granted ownership of these devices. console.perms(5)
explains how to do this.
The driver supports multiple device nodes. The USB framework supports
a maximum of sixteen device nodes (up to minor device number 96).
When you plug in one camera, it will use the first device node (dc2xx0
in the example above). A second camera will use the second device node,
and so on.
SANITY TESTING
First: if you've got /proc support, make sure that the driver has hooked
itself up correctly.
- You should see an entry in /proc/bus/usb/drivers for "dc2xx",
if you enabled USB /proc support and correctly mounted the
usbdevfs on /proc/bus/usb.
Second: when you connect your camera to the computer, does it get recognized
by the driver? (Make sure the camera is powered on!)
- if you've got /proc/bus/usb/devices, you should see an entry
something like this. The "ProdID" may be different if you didn't
plug in a DC-240, as may the strings presented, but "Driver=dc2xx"
had better be there.

E: Ad=82(I) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
- see if "dmesg" output tells you that you plugged in your camera.
Manufacturer: Eastman Kodak Company
Product: KODAK DC240 Zoom Digital Camera
dc2xx.c: USB Camera #0 connected
Third: (optional) can you use gPhoto to talk to the camera?
- When you configure your camera, tell it to use "/dev/usb/dc2xx0"
(or whatever name you used). Right now, gPhoto emits a diagnostic
message (non-GUI) saying that it since it didn't act like a TTY,
it's assuming it's got a USB connection.
- With the camera turned on, get the "camera summary". It'll
talk to the camera -- and tell you you're using USB.
If you got that far, you should be able to use everything fine.
ADDITIONAL INFORMATION
You may find that you need more driver-specific information, which is
currently accessible through a link from http://www.linux-usb.org/
along with other Linux USB resources.

Say Y here if you want to connect this type of still camera to your
computer's USB port. See <file:Documentation/usb/dc2xx.txt> for
more information; some non-Kodak cameras may also work with this
driver, given application support (such as <http://www.gphoto.org/>).
This code is also available as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called dc2xx.o. If you want to compile it as a
module, say M here and read <file:Documentation/modules.txt>.
CONFIG_USB_MDC800
Say Y here if you want to connect this type of still camera to
your computer's USB port. This driver can be used with gphoto 0.4.3

* USB driver for Kodak DC-2XX series digital still cameras

* and have fun!
*
* This should also work for a number of other digital (non-Kodak) cameras,
* by adding the vendor and product IDs to the table below. They'll need
* to be the sort using USB just as a fast bulk data channel.
*/
/*
* HISTORY
*
* 26 August, 1999 -- first release (0.1), works with my DC-240.
* The DC-280 (2Mpixel) should also work, but isn't tested.
* If you use gphoto, make sure you have the USB updates.
* Lives in a 2.3.14 or so Linux kernel, in drivers/usb.
* 31 August, 1999 -- minor update to recognize DC-260 and handle
* its endpoints being in a different order. Note that as
* of gPhoto 0.36pre, the USB updates are integrated.
* 12 Oct, 1999 -- handle DC-280 interface class (0xff not 0x0);
* added timeouts to bulk_msg calls. Minor updates, docs.
* 03 Nov, 1999 -- update for 2.3.25 kernel API changes.
* 08 Jan, 2000 .. multiple camera support
* 12 Aug, 2000 .. add some real locking, remove an Oops
* 10 Oct, 2000 .. usb_device_id table created.
* 01 Nov, 2000 .. usb_device_id support added by Adam J. Richter
* 08 Apr, 2001 .. Identify version on module load. gb
*
* Thanks to: the folk who've provided USB product IDs, sent in
* patches, and shared their successes!

* This identifier is intended to be "stable", reflecting physical paths in

* USB hubs. That makes it stay the same until systems are physically
* reconfigured, by re-cabling a tree of USB devices or by moving USB host
* controllers. Adding and removing devices, including virtual root hubs
* in host controller driver modules, does not change these path identifers;
* neither does rebooting or re-enumerating. These are more useful identifiers
* than changeable ("unstable") ones like bus numbers or device addresses.
*
* With a partial exception for devices connected to USB 2.0 root hubs, these
* identifiers are also predictable: so long as the device tree isn't changed,
* plugging any USB device into a given hub port always gives it the same path.
* Because of the use of "companion" controllers, devices connected to ports on
* USB 2.0 root hubs (EHCI host controllers) will get one path ID if they are
* high speed, and a different one if they are full or low speed.
