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

23WHAT YOU NEED:
24
25- USB support
26- VIDEO4LINUX support
27
28More information about USB support for linux can be found at:

32MODULE OPTIONS:
33
34When the driver is compiled as a module you can also use the 'flickerless'
35option. With it exposure is limited to values that do not interfere with the
36net frequency. Valid options for this option are 0, 50 and 60. (0=disable,
3750=50hz, 60=60hz)

40KNOWN PROBLEMS:
41
42The driver works fine with the usb-ohci and uhci host controller drivers,
43the default settings also work with usb-uhci. But sending more than one bulk
44transfer at a time with usb-uhci doesn't work yet.
45Users of usb-ohci and uhci can safely enlarge SE401_NUMSBUF in se401.h in
46order to increase the throughput (and thus framerate).
