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 | ||
