FW reply different command for different driver. There only is one driver. This driver. This all sounds backwards around. Normally the driver asks the firmware what version it is. From that, it knows what operations the firmware supports, and hence what it can offer to user space. So what is your long terms plan? How do you keep backwards compatibility between the driver and the firmware? Andrew
