UCD90320: UCD90320 can't be found

Part Number: UCD90320


Hi Yihe:

Since we need to comply with MCTP for rule of address, so we add a address translator (LTC4317CDHC, XOR) on SMBUS.

Here's the topology.

Hardware setting of UCD90320 is 0x33.

On the host side, address of UCD90320 is 0x6C.

We found UCD90320 can't be found by GPI from host side.

So we want to check with you:

1. If 0x6C is a acceptable address for GUI?

2. For hardware connection, do we need to connect Alert pin to USB-to-GPIO Adapter?
