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 | |||
