In a word - hardware. Many of the devices the fpgala firmware could run on have only a UART interface between the USB interface and the FPGA. I think Iztok is trying to move towards having a common high level register interface that works the same over UART, SPI, I2C or any control bus. > You are making the number one USB mistake and I think you can do a > lot better here.

That would be very helpful. Beware though: The protocol will only be relevant to devices with an FX2 on board.
