| 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: |

| |
| |
| 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). |
