===========
This driver attempts to support the video and audio streaming capabilities of
the devices mounting the SONiX SN9C101, SN9C102 and SN9C103 (or SUI-102) PC
Camera Controllers.

of the above chips.
The driver relies on the Video4Linux2 and USB core modules. It has been
designed to run properly on SMP systems as well.
The latest version of the SN9C10x driver can be found at the following URL:
http://go.lamarinapunto.com/
4. Module dependencies
http://www.linux-projects.org/
Some of the features of the driver are:
- full compliance with the Video4Linux2 API (see also "Notes for V4L2
application developers" paragraph);
- available mmap or read/poll methods for video streaming through isochronous
data transfers;
- automatic detection of image sensor;
- support for any window resolutions and optional panning within the maximum
pixel area of image sensor;
- image downscaling with arbitrary scaling factors from 1, 2 and 4 in both
directions (see "Notes for V4L2 application developers" paragraph);
- two different video formats for uncompressed or compressed data (see also
"Notes for V4L2 application developers" paragraph);
- full support for the capabilities of many of the possible image sensors that
can be connected to the SN9C10x bridges, including, for istance, red, green,
blue and global gain adjustments and exposure (see "Supported devices"
paragraph for details);
- use of default color settings for sunlight conditions;
- dynamic I/O interface for both SN9C10x and image sensor control (see
"Optional device control through 'sysfs'" paragraph);
- dynamic driver control thanks to various module parameters (see "Module
parameters" paragraph);
- up to 64 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 hotplugging;
- no known bugs.

This driver supports two different video formats: the first one is the "8-bit
Sequential Bayer" format and can be used to obtain uncompressed video data
from the device through the current I/O method, while the second one provides
"raw" compressed video data (without the initial and final frame headers). The
compression quality may vary from 0 to 1 and can be selected or queried thanks
to the VIDIOC_S_JPEGCOMP and VIDIOC_G_JPEGCOMP V4L2 ioctl's. For maximum
flexibility, the default active video format depends on how the image sensor
being used is initialized (as described in the documentation of the API for the
image sensors supplied by this driver).
