| 6 | INTRODUCTION: |
| 7 | |
| 8 | The SE401 chip is the used in low-cost usb webcams. |
| 9 | It is produced by Endpoints Inc. (www.endpoints.com). |
| 10 | It interfaces directly to a cmos image sensor and USB. The only other major |
| 11 | part in a se401 based camera is a dram chip. |
| 12 | |
| 13 | The following cameras are known to work with this driver: |
| 14 | |
| 15 | Aox se401 (non-branded) cameras |
| 16 | Philips PVCV665 USB VGA webcam 'Vesta Fun' |
| 17 | Kensington VideoCAM PC Camera Model 67014 |
| 18 | Kensington VideoCAM PC Camera Model 67015 |
| 19 | Kensington VideoCAM PC Camera Model 67016 |
| 20 | Kensington VideoCAM PC Camera Model 67017 |

| 23 | WHAT YOU NEED: |
| 24 | |
| 25 | - USB support |
| 26 | - VIDEO4LINUX support |
| 27 | |
| 28 | More information about USB support for linux can be found at: |
| 29 | http://www.linux-usb.org |
| 30 | |
| 31 | |
| 32 | MODULE OPTIONS: |
| 33 | |
| 34 | When the driver is compiled as a module you can also use the 'flickerless' |
| 35 | option. With it exposure is limited to values that do not interfere with the |
| 36 | net frequency. Valid options for this option are 0, 50 and 60. (0=disable, |
| 37 | 50=50hz, 60=60hz) |
| 38 | |
| 39 | |
| 40 | KNOWN PROBLEMS: |
| 41 | |
| 42 | The driver works fine with the usb-ohci and uhci host controller drivers, |
| 43 | the default settings also work with usb-uhci. But sending more than one bulk |
| 44 | transfer at a time with usb-uhci doesn't work yet. |
| 45 | Users of usb-ohci and uhci can safely enlarge SE401_NUMSBUF in se401.h in |
| 46 | order to increase the throughput (and thus framerate). |
| 47 | |
