--1386611826-1974767226-1081874913=:26184 Content-Type: TEXT/PLAIN; charset=US-ASCII search the archives of this mailing list. this topic gets discussed quite a bit. basically, you install a usb packet sniffer on windows machine, and do some string of simple operations in the windows software, like: 1. plug and un-plug device 2. plug device and take the smallest, lowest quality pic you can 3. plug device and change some setting in windows software, and take another pic, then another setting, another pic, etc. then, copy the resulting sniffer log to your linux/unix box, and shred it for readability. (if using benoit's usbsnooper, (which i recommend) the attached script i wrote works well) then, stare at the data, and see what patterns you can recognize. then, write a small c program that uses libusb to send packets to the device in linux, one packet at a time, and see what happens. if you dont burn the device up in the process :) you will end up with enough understanding of how it communicates to then look at writing a sane backend. allan On Mon, 12 Apr 2004, Greg Apessos wrote: > my Ezonics EZCam USB III webcam.
