INTRODUCTION:
Cameras with chip from S&Q Technologies are often called DSC(2770) cameras.
They have USB Vendor:Product number 0x2770:0x9120, and are classified as
Class:Subclass:Protocol ff:ff:ff (proprietary:proprietary:proprietary).

further progress with your camera will depend upon your input.
Moreover, the Gphoto project tries very hard to keep a complete list of
all supported cameras, by name and/or by any other distinguishing features,
such as a model number if any is printed on the camera or on the packaging.
If your camera is not on the list of supported cameras, then even if it works
please report it, so that it can be explicitly added by name in the listing
found in the source file camlibs/sq905/library.c. Please do this to help
others. A camera is not sold with the USB vendor:product number printed on
the package. Also even if it works perfectly in Linux with Gphoto software
it will usually not say that on the package, either. For these reasons,
again, please remember to report your camera if it is previously unlisted,
even if it works.

them, or similar chips from SQ. The cameras do distinguish themselves from

Unfortunately, it does not seem possible to do any of these things with
commands sent from the computer even if the camera is tethered, except for
the fact that for some of the cameras the command which triggers capture also
has the effect of deleting everything stored on the camera. Thus, deletion
of all photos may work for your camera, but it may not.

take a photo which can be downloaded later on, through normal photo download
procedures. But the hardware seems unable to support "gphoto2 --capture".
The sq905 cameras can function as webcams. A Sourceforge project called
"sqcam" provides the needed kernel support. If you want to use that module,
remember that you cannot use a libgphoto2 camlib while the module for the
same camera is installed. For, the camlib and the module will fight over
the camera, and the camlib will lose.
The sq905 cameras can function as webcams. Support for the webcam mode of
these cameras is available through the module gspca_sq905, included as
part of the regular kernel since kernel version 2.6.29. This means it is
part of the kernel source, of course. It is then up to your distro to
include the webcam support for these cameas, or not. The webcam mode for
any of these cameras can do streaming at any of the resolutions 160x240,
176x144, 320x240, 352x288, and in addition at 640x480 provided that the
camera's hardware will do this (What is the max resolution for still photos?
The same applies in webcam mode). However, do not expect a high frame rate
in webcam mode. The camera is a USB 1.1 device, and it is streaming
uncompressed frames, using bulk transport, not isochronous transport.
Thanks is hereby given to the authors and maintainers of the old "sq"
module, which for several years provided an out-of-kernel module to support
streaming with these cameras.
