└─>USB OV511 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 ov511 / ov518 support of the gspca module
you need atleast version 0.6.0 of libv4l.

Say Y here if you want to connect this type of camera to your
computer's USB port. See Documentation/video4linux/ov511.txt
for more information and for a list of supported cameras.

To compile this driver as a module, choose M here: the
module will be called ov511.
