Who can help me with some information about the existing USB chips... There are a lot of suppliers and kind of USB chips for HID, Audio, Video. The project I am on now is creating a serial data logger. I use a spy microcontroller board witch catches the RS232 data between 2 devices. The board then has to send the data it receives through USB to the computer (delphi software). I want to use my own protocol en just need a USB chip that sends what I want to send. Could someone please give me some more information about this?
