TSER953: product ID is equal to "UB953"

Hello.

While reading device ID register of TSER953 by I2C, we get the "UB953" value.

And we can see no overall registers difference between UB953 and TSER devices.

The question is - how can we distinguish by a software, what the device is installed on the board  UB953 or TSER953?

Thank you.
