└─>USB W996[87]CF JPEG Dual Mode Camera support (DEPRECATED)
In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
This driver is DEPRECATED please use the gspca ov519 module
instead. Note that for the w9968cf support of the gspca module
you need atleast version 0.6.3 of libv4l.

Say Y here if you want support for cameras based on OV681 or
Winbond W9967CF/W9968CF JPEG USB Dual Mode Camera Chips.

This driver has an optional plugin, which is distributed as a
separate module only (released under GPL). It allows to use higher
resolutions and framerates, but cannot be included in the official
Linux kernel for performance purposes.

See Documentation/video4linux/w9968cf.txt for more info.

To compile this driver as a module, choose M here: the
module will be called w9968cf.
