LSM9DS0 Gyro problem

I try to set up LSM9DS0 IMU for my balancing robot.
I use STM32 Discovery and I2C to communicate with sensor. Accelerometer works fine becouse of what I am sure I2C and connections are OK. Unfortunitely Gyro sends the same values all the time.

My configuration is:
CTRL_REG1_G (0x20): 0xff
CTRL_REG2_G (0x21): 0x00
CTRL_REG3_G (0x22): 0x00
CTRL_REG4_G (0x23): 0x00
CTRL_REG5_G (0x24): 0x00

Does someone have some expirience with this sensor and can point me what is wrong or send working configuration?

Best regards,
