I don't think you have written that you have a particular latency

Hi,
I'm using a USB Inertial Measurement Unit that theoretically produces data at
500Hz. According to the timestamps on the data, indeed the data is being
produced at 500Hz. But I'm getting it in burst, with an "efective" sampling
rate of 6ms instead of 2ms. That is, 166Hz instead of 500hz.
