We need to have a simple & cheap firmware to test the maximum throghput and/or the current speed for the usb network upto 480Mbps at USB2.0 full speed mode. Since the throughput test for the PC host USB chipset should be included in the tester, a dummy data transfered bewteen PC and tester should be used for bulk transfer mode at high speed. This project involve hardware circuit design and software programming for the hardware chips on the tester side and PC host side. Please recommend your cheapest embedded usb chipset solution (with minimum pin count)to us as our pimary considerations. The display for the speed measured should be shown on the PC's task bar or on top of screens. At the end of the project, you should supply the correponding circuit diagram, program source code, a working demo shipped to us at your cost. You can propose at higher rate if necessary. The PCB layout is optional, you may provide the demo board with a propotyping or a full PCB layout board (with corrsponding circuit & layout diagram). If you are expert either to window driver or assembly programming only, you can bid for partial project development only. We can consider joint development with several parties.
