INTRODUCTION:
|
|
|
|
The SE401 chip is the used in low-cost usb webcams.
|
|
It is produced by Endpoints Inc. (www.endpoints.com).
|
|
It interfaces directly to a cmos image sensor and USB. The only other major
|
|
part in a se401 based camera is a dram chip.
|
|
|
|
The following cameras are known to work with this driver:
|
|
|
|
Aox se401 (non-branded) cameras
|
|
Philips PVCV665 USB VGA webcam 'Vesta Fun'
|
|
Kensington VideoCAM PC Camera Model 67014
|
|
Kensington VideoCAM PC Camera Model 67015
|
|
Kensington VideoCAM PC Camera Model 67016
|
|
Kensington VideoCAM PC Camera Model 67017

WHAT YOU NEED:
|
|
|
|
- USB support
|
|
- VIDEO4LINUX support
|
|
|
|
More information about USB support for linux can be found at:
|
|
http://www.linux-usb.org
|
|
|
|
|
|
MODULE OPTIONS:
|
|
|
|
When the driver is compiled as a module you can also use the 'flickerless'
|
|
option. With it exposure is limited to values that do not interfere with the
|
|
net frequency. Valid options for this option are 0, 50 and 60. (0=disable,
|
|
50=50hz, 60=60hz)
|
|
|
|
|
|
KNOWN PROBLEMS:
|
|
|
|
The driver works fine with the usb-ohci and uhci host controller drivers,
|
|
the default settings also work with usb-uhci. But sending more than one bulk
|
|
transfer at a time with usb-uhci doesn't work yet.
|
|
Users of usb-ohci and uhci can safely enlarge SE401_NUMSBUF in se401.h in
|
|
order to increase the throughput (and thus framerate).
