Allow me to rephrase:<p>You want to connect a microcontroller to a USB hub controller (and LCD display or memory) then send commands to the webcam and recieve image data back to your controller where you will process it and send it ot a memory card or LCD display.<p>Is this what you are trying to do?<p>Webcams often use the TWAIN driver like scanners do. Perhaps you can study this driver protocol. Depending you the camera you have, there may need to be some additional customization for your hardware.<p>Camera Twain Driver OCX<p>What is TWAIN

There're some camera moduls with built-in jpeg compressing engine and external bus, they are very easy to interface to micorcontroller. Vendors include Agilent, Fujitsu, NEC etc. There're also many OEM in my city.<p>mike
