(www.endpoints.com). +It interfaces directly to a cmos image sensor and USB. The only other major +part in a se401 based camera is a dram chip. + +The following cameras are known to work with this driver: + +Aox se401 (non-branded) cameras +Philips PVCV665 USB VGA webcam 'Vesta Fun' +Kensington VideoCAM PC Camera Model 67014 +Kensington VideoCAM PC Camera Model 67015 +Kensington VideoCAM PC Camera Model 67016 +Kensington VideoCAM PC Camera Model 67017 + + +WHAT YOU NEED: + +- USB support +- VIDEO4LINUX support + +More information about USB support for linux can be found at: +http://www.linux-usb.org + + +MODULE OPTIONS: + +When the driver is compiled as a module you can also use the 'flickerless' +option. With it exposure is limited to values that do not interfere with the +net frequency. Valid options for this option are 0, 50 and 60. (0=disable, +50=50hz, 60=60hz) + + +KNOWN PROBLEMS: + +The driver works fine with the usb-ohci and uhci host controller drivers, +the default settings also work with usb-uhci. But sending more than one bulk +transfer at a time with usb-uhci doesn't work yet. +Users of usb-ohci and uhci can safely enlarge SE401_NUMSBUF in se401.h in +order to increase the throughput (and thus framerate). + + +HELP: + +The latest info on this driver can be found at: +http://www.chello.nl/~j.vreeken/se401/ +And questions to me can be send to: +pe1rxq@amsat.org |
