If doing it via HID is a pain, then "analog mode" is usually set manually with a button on the device itself. If, as you mention, you need to set this more or less permanently at every startup, then you could solder a wire across the button terminals to force it to analog mode. I've done this for some hacked gamecontroller stuff I did a while back.

does anybody know if it is possible to send “analog on/off” to a hid device? If yes – how?
