We used a PIC chip. I'm not sure which one we used, but 6 are listed at: http://www.microchip.com/ParamChartSearch/chart.aspx?branchID=111&mid=10&lang=en&pageId=74 The PIC16C765 looks to have a low-speed USB interface and a serial interface(USART), so that is the cheapest PIC chip that satisfies your I/O needs. You will notice that even the most expensive PIC18F4550, only has 32K of ROM and 2K or RAM, so running Linux on something this small is out of the question. I assume using PIC chips requires assembly language programming. Hope That Helps.
