high frequency problem

hello,
I would like to implement a high frequency system detecting movements and giving raw data to the pc for further elaboration. I'd like the imu 3000 or the mpu6050 to give gyro and accel data via usb at 1kHz sampling frequency. Currently, modifying the roll dice source of the imu3000 I managed to get raw data at a frequency of 20Hz. Is it possible to increase this frequency?
how can I do it?
thanks for the help provided!
Bye
Marta
