- Linux driver for SE401 based USB cameras
- Copyright, 2001, Jeroen Vreeken
- 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).
- HELP:
