| 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). | |
