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:

WHAT YOU NEED:
|
| 24 |
|
|
|
| 25 |
|
|
- USB support
|
| 26 |
|
|
- VIDEO4LINUX support
|
| 27 |
|
|
|
| 28 |
|
|

|
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 |
|

|
|
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 then 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).
