Power Management USB UNIT Latch-Up

I am using the TPS65920 Power-Management

and System Companion Devices.

Hence on some circumstances when we reset the CPU in order to reboot the systems

we see the following phenomena. 

Reading USB unit of the I2C space (0x48) caused most of registers to be read as 0x11  sometimes also othe value like 0x72 some registers are just 0.

The other device in 0x49,0x4A and 0x4B seems to be read OK.

My question is: could I reset the USB companion of that device from the CPU space via the i2C ?
