3. Overview
===========
This driver supports the video streaming capabilities of the devices mounting
Winbond W9967CF and Winbond W9968CF JPEG USB Dual Mode Camera Chips, when they
are being commanded by USB.
The driver relies on the Video4Linux, USB and I2C core modules of the Linux
kernel, version 2.6.0 or greater, and is not compatible in any way with
previous versions. It has been designed to run properly on SMP systems
as well. At the moment, an additional module, "ovcamchip", is mandatory; it
provides support for some OmniVision CMOS sensors connected to the W996[87]CF
chips.
The driver is split into two modules: the basic one, "w9968cf", is needed for
the supported devices to work; the second one, "w9968cf-vpp", is an optional
module, which provides some useful video post-processing functions like video
decoding, up-scaling and colour conversions. These routines can't be included
into official kernels for performance purposes. Once the driver is installed,
every time an application tries to open a recognized device, "w9968cf" checks
the presence of the "w9968cf-vpp" module and loads it automatically by default.
Up to 32 cameras can be handled at the same time. They can be connected and
disconnected from the host many times without turning off the computer, if
your system supports the hotplug facility.
To change the default settings for each camera, many paramaters can be passed
through command line when the module is loaded into memory.
The latest and full featured version of the W996[87]CF driver can be found at:
http://go.lamarinapunto.com/
The "ovcamchip" module is part of the OV511 driver, version 2.25, which can be
downloaded from internet:
http://alpha.dyndns.org/ov511/
To know how to patch, compile and load it, read the paragraphs below.
4. Supported devices
====================
At the moment, known W996[87]CF based devices are:
- Aroma Digi Pen ADG-5000 Refurbished
- AVerTV USB
- Creative Labs Video Blaster WebCam Go
- Creative Labs Video Blaster WebCam Go Plus
- Die Lebon LDC-D35A Digital Kamera
- Ezonics EZ-802 EZMega Cam
- OPCOM Digi Pen VGA Dual Mode Pen Camera
If you know any other W996[87]CF based cameras, please contact me.
The list above does NOT imply that all those devices work with this driver: up
until now only webcams that have a CMOS sensor supported by the "ovcamchip"
module work.
For a list of supported CMOS sensors, please visit the module author homepage:
http://alpha.dyndns.org/ov511/
Possible external microcontrollers of those webcams are not supported: this
means that still images can't be downloaded from the device memory.
Furthermore, it's worth to note that I was only able to run tests on my
"Creative Labs Video Blaster WebCam Go". Donations of other models, for
additional testing and full support, would be much appreciated.
5. Kernel configuration and third-part module compilation
=========================================================
As noted above, kernel 2.6.0 is the minimum for this driver; for it to work
properly, the driver needs kernel support for Video4Linux, USB and I2C, and a
third-part module for the CMOS sensor.
The following options of the kernel configuration file must be enabled and
corresponding modules must be compiled:
# Multimedia devices
#
CONFIG_VIDEO_DEV=m
# I2C support
#
CONFIG_I2C=m
The I2C core module can be compiled statically in the kernel as well.
# USB support
#
CONFIG_USB=m
In addition, depending on the hardware being used, just one of the modules
below is necessary:
# USB Host Controller Drivers
#
CONFIG_USB_EHCI_HCD=m
CONFIG_USB_UHCI_HCD=m
CONFIG_USB_OHCI_HCD=m
Also, make sure "Enforce bandwidth allocation" is NOT enabled.
# USB Multimedia devices
#
CONFIG_USB_W9968CF=m
The last module we need is "ovcamchip.o". To obtain it, you have to download
the OV511 driver, version 2.25 - don't use other versions - which is available
at http://alpha.dyndns.org/ov511/ . Then you have to download the latest
version of the full featured W996[87]CF driver, which contains a patch for the
"ovcamchip" module; it is available at http://go.lamarinapunto.com .
Once you have obtained the packages, decompress, patch and compile the
"ovcamchip" module. In other words:
[user@localhost home]$ tar xvzf w9968cf-x.x.tar.gz
[user@localhost home]$ tar xvjf ov511-2.25.tar.bz2
[user@localhost home]$ cd ov511-2.25
[user@localhost ov511-2.25]$ patch -p1 < \
/path/to/w9968cf-x.x/ov511-2.25.patch
[user@localhost ov511-2.25]$ make
It's worth to note that the full featured version of the W996[87]CF driver
can also be installed overwriting the one in the kernel; in this case, read the
documentation included in the package.
If everything went well, the W996[87]CF driver can be immediatly used (see next
paragraph).
6. Module loading
=================
To use the driver, it is necessary to load the "w9968cf" module into memory
after every other module required.
For example, loading can be done this way, as root:
[root@localhost home]# modprobe usbcore
[root@localhost home]# modprobe i2c-core
[root@localhost ov511-x.xx]# insmod ./ovcamchip.ko
[root@localhost home]# modprobe w9968cf
At this point the devices should be recognized: "dmesg" can be used to analyze
kernel messages:
[user@localhost home]$ dmesg
There are a lot of parameters the module can use to change the default
settings for each device. To list every possible parameter with a brief
explanation about them and which syntax to use, it is recommended to run the
"modinfo" command:
[root@locahost home]# modinfo w9968cf
7. Module paramaters

8. Credits
==========
The development would not have proceed much further without having looked at
the source code of other drivers and without the help of several persons; in
particular:
- the I2C interface to kernel and high-level CMOS sensor control routines have
been taken from the OV511 driver by Mark McClelland;
- memory management code has been copied from the bttv driver by Ralph Metzler,
Marcus Metzler and Gerd Knorr;
- the low-level I2C read function has been written by Frédéric Jouault, who
also gave me commented logs about sniffed USB traffic taken from another
driver for another system;
- the low-level I2C fast write function has been written by Piotr Czerczak;

This driver has an optional plugin, which is distributed as a

allows you to use higher resolutions and framerates, and can't
be included into the official Linux kernel for performance
purposes.
At the moment the driver needs a third-part module for the CMOS
sensors, which is available on internet: it is recommended to read
<file:Documentation/usb/w9968cf.txt> for more informations and for
a list of supported cameras.
This driver uses the Video For Linux and the I2C APIs.
You must say Y or M to both "Video For Linux" and

Information on this API and pointers to "v4l" programs may be found
on the WWW at <http://roadrunner.swansea.uk.linux.org/v4l.shtml>.
This code is also available as a module ( = code which can be

* Copyright (C) 2001 Greg Kroah-Hartman (greg@kroah.com)
*
* History:
*
* 2001-10-13 - 0.1 js
* - first version
* 2001-11-03 - 0.2 js
* - simplified buffering, one-shot URBs for writing
* 2001-11-10 - 0.3 js
* - removed IOCTL (setting power/mode is more complicated, postponed)
* 2001-11-28 - 0.4 js
* - added vendor commands for mode of operation and power level in open
* 2001-12-04 - 0.5 js
* - set IR mode by default (by oversight 0.4 set VLL mode)
* 2002-01-11 - 0.5? pcchan
* - make read buffer reusable and work around bytes_to_write issue between
* uhci and legusbtower
* 2002-09-23 - 0.52 david (david@csse.uwa.edu.au)
* - imported into lejos project
* - changed wake_up to wake_up_interruptible
* - changed to use lego0 rather than tower0
* - changed dbg() to use __func__ rather than deprecated __FUNCTION__
* 2003-01-12 - 0.53 david (david@csse.uwa.edu.au)
* - changed read and write to write everything or timeout (from a patch by Chris Riesen and
* Brett Thaeler driver)
* - added ioctl functionality to set timeouts
* 2003-07-18 - 0.54 davidgsf (david@csse.uwa.edu.au)
* - initial import into LegoUSB project
* - merge of existing LegoUSB.c driver
* 2003-07-18 - 0.56 davidgsf (david@csse.uwa.edu.au)
* - port to 2.6 style driver
