Zero values while reading raw accel/gyro data on STM32

Hello,

I am trying to connect my MPU-6000 to STM32 microcontroller via I2C. I'd like to read raw data from accels and gyros, but I always get zero values (registers 59-72). But I'm able to read whoami register (117) and it returs the right value - 104, therefore I can claim that I2C communication is ok.
Could you help, please, why do I get always zeros instead of the right accel and gyro values?

Thanks in advance!

Kirill
