How long does it take for the queue to exhaust your memory if you keep
bombarding the driver with requests?

I do not think you need a queue. I believe the nature of LEDs and rumble
force feedback effect is such that you can discard all requests but the
latest that arrived between the moment you submitted a request to the
device and the moment you are ready submit a new one.

Thanks.
