Embedded USB webcam IDENTIFIER hardware

Hi, I need to develop a embedded hardware (with a FPGA, example Xilinx(R) Spartan-3AN FPGA) capable of IDENTIFY what kind of USB web cam is plugged-in (example webcam manufacturer, speed, data transfer rate, etc.), the USB will work with USB 1.0 or USB 1.1 (not USB 2.0) so a USB 2.0 web cam will work at USB 1.1. Due this is a embedded design, no computer interaction is required (this means that the USB web cam will not be plugged-in to a computer).



Any idea about it



Thanks in advanced. Warner

1) This is an embedded processor task, not an FPGA task. Find one with USB host mode, or use a SPI-controllable USB host chip 2) Your best bet is to query the VID/PID and look it up in a database to determine the other parameters
