MPU9150 was working fine, and suddenly zero readings

Hi everyone,

I have done a 3D mouse with MPU9150 and everything was working fine, but now, I just get zeros in accel and gyro, or a random value but always the same value, it doesn't response to my moves, I have tried to power cycle, restart the sensor by writing zeros to all but 2 registers, re-initialize, and nothing works, this problem has happened in 4 of the 10 PCB's I have.

Somebody has any idea?

thanks.
